Loop in amdp method Context This blog post has a post reference to my previous blog post, where I had explained a scenario which involved aloading scenario where data target was an aDSO having several source aDSOs with similar structure. What are AMDP, CDS, and CDS Table Functions? AMDP (ABAP Managed Database Procedure): AMDP is a database procedure written in SQL and managed in the ABAP layer. 4+ Syntaxes / ABAP Expressions to read all the posts from the series ABAP 7. The name of the current database schema must not be specified here. avoid loops, further joins, formatting or data conversions. We can create our class method for AMDP using exporting, importing, changing parameters. Create a new class zjp_flight_class and add an AMDP Marker interface. AMDP - A Quick Code Start Let's start with how the syntax looks like for the AMDP class and method: CLASS amdp_class DEFINITION. The call of an AMDP method is same as normal ABAP method called from a program. As well as the restrictions for the parameter interface of an AMDP method described under AMDP, the following restrictions apply in An AMDP function implementation is indicated as an AMDP method in the implementation part of the class using the addition BY DATABASE FUNCTION of the statement METHOD. For HANA Database- the interface – IF_AMDP_MARKER_HDB – the suffix HDB indicates the database system for which the ABAP managed database procedure can be implemented in the AMDP method of AMDP class. If yes please help me with an example. 目录 AMDP介绍 AMDP语法 DECLARE CURSOR AMDP介绍 AMDP（ABAP-Managed Database Procedure）是在ABAP层进行HANA数据库过程的实现和生命周期的管理，使用ABAP开发语言在ADT工具编HANA SQLScript。允许ABAP开发人员在HANA数据库层直接编写应用逻辑，即所谓的数据库存储过程。AMDP类只能在ADT里进行开发，在SAP GUI里可以用 I have the following AMDP: Method GET_COUNT by database PROCEDURE FOR HDB LANGUAGE SQLSCRIPT. This insert with select * , inserts all columns in the DB table. Instead of using demo database tables, CDS view entities are used in the `USING` list. AMDP method CLASS zcl_demo_amdp DEFINITION PUBLIC FINAL CREATE PUBLIC . Accessing tables from different schema through AMDP. My requirement is to DO loop in SAP ABAP is an unconditional loop that executes a block of code several times without providing a specific condition. INTERFACES if_amdp_marker_hdb . Here we have used inner join on database table with input parameter table. g. I will have a req table and stock table . Loop table records using For Loop. IV_Parent is the input partner and ev_top_parent is the output value. Create a transformation and create a end routine using AMDP script - 2. options READ-ONLY using Alpha Beta Gamma. control structures like IF, WHILE LOOP, Cursors ) which can be used for such scenarios if really necessary. Returning parameter I have created AMDP Procedure method to get the top-parnet and below given is the logic implemented in AMDP method. In above code, we are using colons(:) before variable lt_abap_data. To preserve the original implementation for performance and What if AMDP method itself has thousands of lines of code with multiple AMDP methods call with in an AMDP method. I have to populate some fields in TAB1 based on the values in TAB2 (using the value to calculate result based on a formula). As shown in the mapping tables, the elementary ABAP types of interface parameters of an AMDP method are mapped to the appropriate types in SQLScript. Remember, interfaces can only be added in PUBLIC SECTION. As with any other Pay attention to AMDP method implementation syntax. Write subsequent select statement One good feature of AMDP is that one can write The method SELECT_SPFLI_BY_MAX_FLTIME is an AMDP procedure implementation where the AMDP scalar function that is implemented in the method GET_MAX_FLTIME_SPFLI is called in its SELECT statement in the WHERE condition. This way, we can handle Select-Options in AMDP. For those of you who are “HANA Beginners” and have a hard time with AMDP - Examples Continue AMDP, Implementation of a SQLScript Procedure AMDP, Calling an AMDP Procedure from SQLScript AMDP, Calling an SQLScript Procedure from AMDP AMDP, AMDP Methods in Interfaces and Superclasses AMDP, SQL Script with Tabular CHANGING Parameter AMDP, AMDP Method with Specified Database Connection AMDP, Filling a Mesh SAP Help Portal - SAP Online Help In this post, you will learn - How to call AMDP from ABAP How to call AMDP from another AMDP This is continuation of post Exploring ABAP on HANA [8] : Introduction to AMDP where below AMDP method was created. There are two tables: TAB1 and TAB2. The constant CALL_AMDP_METHOD of the class CL_ABAP_DBFEATURES can be used to query whether the current database supports AMDP procedures. Can we loop an internal table inside AMDP method. Tabla > - The AMDP example for ABAP for Cloud Development is designed differently compared to the AMDP example for Standard ABAP. Parameter Interface. Maintenance is simplified by consolidating database logic with ABAP development. A: That's typo. AMDP Functions for AMDP Methods Dear All, Yet another very interesting topic in AMDP, which is how to call AMDP method inside AMDP method. For loop with addition record_count( :lt_tab) can be used to loop through the records. If the correct authorization is granted, it is possible to access objects in a AMDP (ABAP Managed Database Procedures): • AMDP is a class that allows us to write the Object Oriented classes at back-end for the views mentioned above. An AMDP procedure implementation cannot be identified as an AMDP method in the declaration part of the class. Well, before moving forward let's see an overview of AMDP is here ABAP Managed Database Procedures - Introduction Accessing tables from different schema through AMDP. The test an AMDP method that implements an SQLScript procedure cannot call any database procedures or use any database functions that themselves use the AMDP procedure or function. An AMDP Method can be defined like a regular static/instance method in any visibility The AMDP procedure implementation must be restricted to reads. I have a simple requirement that i can achieve through Formula in BW4HANA Transformation. • It is able to have multiple result returns on complex logic. Example: An AMDP method with SQLScript logic. Lt_abap_data is created in method itself and need colon to be identified as local variable. Declares the AMDP method as client-dependent when it uses at least one ABAP-Managed Database Procedures (AMDP) are a method of executing database-specific procedures or functions directly from ABAP code, but in a way that is tightly The document defines all statements usable within a database procedure incuding "Control Structures" like IF, WHILE etc. for that we have to create AMDP class and method and inside our method we can call Function module or Bapi. . See below screenshot. With AMDP, We can take advantage of new features of HANA (code push-down Hi All, I tried searching for below issues but could not find resolution I am doing LOOP calculations over internal table in AMDP. In this way, it is easy to code and handles, but low performance. In an AMDP When implemented, all AMDP methods must be flagged using the statement METHOD. The public ABAP class (AMDP class) in this example provides the AMDP method get_flights, which serves as the implementation of thetable function tab_function_example. The AMDP methods must not be blank and must have This site uses cookies and related technologies, as described in our privacy statement, for purposes that may include site operation, analytics, enhanced user experience, or advertising. In an AMDP method, it is possible to access objects in the same database schema directly. btart[ :lv_index ]) = '100' then . Define a static method get_flights Select client specific data inside the AMDP method; Convert the rows to columns using “Case statement" ( Transposition ) Declare internal table inside AMDP class Go to the AMDP class and declare the internal table in the public section. Is this achievable in AMDP procedure . These additions also provide some information about the database and Previously, to sum accumulate or sum total value on the dataset, we will perform it by using LOOPENDLOOP on ABAP program. No nested table/structure allowed for parameters. But be warned: do not try to loop over single reords of result sets. An AMDP procedure implementation is an AMDP method for implementing a database procedure. Is this a typo in the post or also in the coding, because the method is called GET_COUNT. AMDP procedur Its a AMDP procedure , and the internal table contains 5 records and the INSERT with SELECT on the internal tables inserts 5 rows in the DB table. AMDP only works if your DB is HANA We would like to show you a description here but the site won’t allow us. e. Your performance will go down. In the runtime we read the active table of the respective source aDSO using a common transformation between two infosources consisting After coding logic inside AMDP method, you can consume it in ABAP report, or use AMDP same as delegate method in CDS table function. This can slow down your AMDP - Calling an AMDP Procedure from SQLScript (Client-safe) AMDP - AMDP Methods in Interfaces and Superclasses (Client-safe) AMDP - Filling a Mesh with SQLScript (Client-safe) AMDP - AMDP Functions (Client-safe) AMDP - Access to ABAP Types (Client-safe) AMDP - Graph Processing (Client-safe) AMDP - Implementation of an L Procedure (Client-safe) Hello Sahil, in SQLScript there exists also Imperative Statements (e. AMDP Method Call from Program and Calling an AMDP method from another AMDP method Here we have a single AMDP method. Scenario :- The interface IF_AMDP_MARKER_HDB must be added to the public section of the class and then add the method to the class with importing and exporting parameters. The required In below we have two ITables (Internal Table)and in loop , lets fill an ITable and then at end of loop , push the result to the result ITable. The relevant additions are AMDP OPTIONS READ-ONLY in AMDP method declarations and OPTIONS READ-ONLY in AMDP method implementations. Let’s say you implemented a method in ABAP and later discover performance problems; you can implement the method as an AMDP. By leveraging SQLScript and ABAP integration, we can handle complex database operations and In this post, you will learn For Loop for Internal Tables Keyword LET Nested For Loops Visit ABAP 7. CLASS-METHODS: get_acdoca FOR TABLE FUNCTION zchau_cds_001. Lets discuss about few AMDP routines - 1. The code loops through result_package searching for values that have the value type 10 But for any ABAP function or class method there is a way we can use inside our CDS via AMDP, so we call it CDS view with table functions. We would like to show you a description here but the site won’t allow us. Here we can make use of the ABAP syntax and the ABAP datatypes. 文章浏览阅读6. Better don't do it. FOR Iteration for Single They are then created as a SAP HANA procedure that is implemented as a method in an AMDP (ABAP managed database procedure) class. here, ABAP Managed Database Procedures - Introduction. What all operation we can do inside the AMDP method. Can we write delete adjacent duplicate. One of the critical tools in this journey is the ABAP Managed Da ABAP托管数据库过程（ABAP-Managed Database Procedure，以下简称AMDP）是在APAP on SAP HANA开发中的一种优化模式。AMDP使用数据库语言书写，比如Native SQL或者是SQL Script，并且在AMDP类的AMDP方法内实现。因此用它开发数据库 ABAP CDS Table Function Implemented by AMDP ABAP CDS Table Function defines table function which are native to the database. With AMDP procedures, ABAP can easily and elegantly outsource more complex requirements in the SAP HANA database. Define the AMDP Method. as an AMDP method in an AMDP class. I have to prepare a 3rd table which will assign this stock to every requirement . Debug Details-2. * Marker interface with SAP HANA DB as database type Example. One can see here one AMDP method This is the third video of our Real-time AMDP scenario, where we build our internal table and do a loop over the same to compute the union of another table. AMDP Procedure Method: Typically, AMDP is a static method of an ABAP class. The AMDP class is generated by the BW framework and can only be edited in the ABAP Development tools for SAP NetWeaver (ADT). Below is code: declare lv_qty decimal( 13,3 ); FOR lv_index IN 1. lv_count do Retroactive Implementation as AMDP. Furthermore, an AMDP procedure or function can use regular SQL Script procedures and functions created in SAP HANA Studio or using Native SQL. In When used in AMDP, SQL Script replaces calls of database procedures using database procedure proxies and the statement CALL DATABASE PROCEDURE. Call AMDP(ABAP Managed Database Procedure) Inside AMDP Method Step#2: The Method that actually implements the AMDP procedure code must have some specialized method additions to identify itself as an AMDP. 2. inside AMDP method. How to declare internal table in AMDP? A common requirement in AMDP is to declare and use a runtime table or internal table. However, an optional addition AMDP OPTIONS can be used to declare attributes of the AMDP method. It applies when specified either in the implementation or in the declaration of the method, or both. Standard program AMDP method declarations must use one of the following additions and specify particular objects in the USING list: CDS SESSION CLIENT DEPENDENT. AMDP procedure implementations with the addition BY DATABASE PROCEDURE; AMDP function implementations with the addition BY DATABASE FUNCTION; The implementation of an AMDP method is stored in the ABAP database schema by the ABAP runtime framework. 9k次，点赞11次，收藏45次。本文详细介绍了AMDP（ABAP-Managed Database Procedure），包括其在ABAP中的应用、语法特性、变量声明、游标操作、数组使用、条件判断、内表读取、方法嵌套及函数与过程实现。通过实例展示了如何在HANA数据库层编写和调用AMDP函数和过程。 an AMDP method that implements an SQLScript procedure cannot call any database procedures or use any database functions that themselves use the AMDP procedure or function. Debug Details-1. My variable is always blank and not adding MENGE value : ct_vbap_new is the internal table. You may choose to manage your own preferences. For a material i have 3 req and stock is in 1 line with sufficient quantity. WRITE: / ls_row-column1, ls_row-column2. Then we can use the AMDP class method in side our CDS view to achive our requarement but compare Introduction to AMDP in Business add in: Revolutionizing ABAP Development As businesses move towards SAP HANA, leveraging its in-memory computing capabilities becomes essential for developing efficient and high-performing applications. They leverage SAP HANA’s in-memory processing for improved performance. It is a fundamental construct that facilitates the iterative execution of a code block DATA: lt_result TYPE TABLE OF my_table. But to explore i chose to create a AMDP in End routine. To achieve this, we can leverage HANA SQL functions to . ->The CDS table function has a set of input parameters and a set of return 1. It allows developers to execute Hi Gurus, I' new to AMDP still exploring the area. When implemented, all AMDP methods must be flagged using the statement METHOD. • Debugger can be put Hello Expert, Please help me for the below points: 1. (if_amdp_marker_hdb) Refer Object Oriented ABAP [1] : Introduction to ABAP Class if you need help with this. LOOP AT lt_result INTO DATA(ls_row). Notes The ABAP Development Tools (ADT) are better suited for the editing of database procedures and functions in AMDP methods than Class Builder in ABAP Workbench. We can see the AMDP class The option READ-ONLY can also be specified with the addition AMDP OPTIONS in the declaration of an AMDP method. • It is a simple ABAP class method. abap Add interface IF_AMDP_MARKER_HDB. SQLScript Procedures. This generated class generated by BW and only edited in the ABAP development tool. The parameter interface of an SQL Script procedure uses input parameters declared using IN, output parameters declared using OUT, and input/output parameters declared using In AMDP classes, AMDP methods are flagged as followed: In AMDP procedure implementations and AMDP function implementations that do not implement any CDS table functions, flagging is not necessary in the declaration with METHODS or CLASS-METHODS. • It can process and modify the data on the database layer. begin. Declaring the global table types are Is there a way we can achieve loop at internal table in AMDP procedure . lt_bseglog = select * from 1. PUBLIC SECTION. Test the AMDP Procedure with report. if (:lt_fmifiit. Table Function Implementation. You only have to consider that this will be very slow from a performance point of view. Depending on what you have written I think the requirement can also be implemented using a AMDP - Procedure Implementations. But be warned: do not try to loop over single reords of AMDP CLASS – An AMDP class is a global class that contains special tag interface that starts with – IF_AMDP_MARKER_* . In an AMDP Ob die aktuelle Datenbank AMDP-Prozeduren unterstützt kann über die Konstante CALL_AMDP_METHOD der Klasse CL_ABAP_DBFEATURES abgefragt werden. I have a requirement like . It is declared in an AMDP class like a regular static method or instance method in any visibility section. The result is as below – Code In Text "AMDP with Select Option CLASS zjp_so_amdp_class DEFINITION PUBLIC FINAL CREATE PUBLIC . Here i have implemented a recursive logic with the WHILE loop to get the top most hierarchy partner from the same table BUT050. Create a method definition. SAP Community; Groups; Interest Groups; you can have a look at method AMDP_GET_BP_CLASSIFICATION in Class CL_EPM_OIA_BP_CLASSIFY_AMDP (should Key Features of AMDP: SQLScript procedures are defined and executed within the ABAP environment. declare V_SPC integer := 0; - In your LOOP method GE_COUNT is called. Here we have a simple class Hi Kailash, The document defines all statements usable within a database procedure incuding "Control Structures" like IF, WHILE etc. --loop on table data lt_scarr = select * from scarr where mandt = loop itab assign <fs>select b1 b2 from dbtable where field1 = <fs>-field1 etcendloop. This blog demonstrated how to create and consume an AMDP method in a report program with select-options. CALL METHOD zcl_amdp_demo=>get_data IMPORTING result = lt_result. AMDP functions can be defined that can be accessed only in other AMDP methods and functions defined that implement CDS table functions. This method is having input and export parameter only pass by value. The Goal of AMDP implementation is always to remove any additional logic required at the abap layer i. Furthermore, an AMDP procedure or function can use regular SQL Script procedures and functions created in SAP Web IDE for SAP HANA or using Native SQL. So, if I want to use window HANA SQL Script - Internal Table with different operations The post describes how to use HANA SQL Script to declare Internal table in AMDP and few operations like SEARCH, READ etc. Before moving forward let's see an overview of AMDP and other intresting stuff is. 4 and beyond. Scenario 2) If you are using any method of same AMDP class or When you create a AMDP script transformation a SAPHANApocedure created that is implemented by a method in AMDP Class. Thanks & Best Regards, Kailash Elementary and tabular method parameters become scalar and tabular parameters of the database procedure respectively. Create a class and method using HANA studio which automatically populates definition and implementation Modified the class method to add interface IF_AMDP_MARKER_hdb Added a Type and table to be Hi All, Today I am here to quickly show you a useful technique for making loops (index-based cell access) in SQLScript the same way you can in ABAP. These options are optional, with the following exception: READ-ONLY must be specified at least once in the implementation of an AMDP function or an Solved: Hello Experts, i have to check condition for two fields in AMDP , currently i have written the select query in amdp then i used a abap program to calculate the. Define an AMDP method in the desired visibility section (public, private, or protected) with the following parameter restrictions: Generic types like TYPE ANY are not In order to connect your Hana DB and AMDP we must give the marker interface: IF_AMDP_MARKER_HDB. 3. The following sections describe the components of AMDP: AMDP - Classes; AMDP - Methods; AMDP - Inheritance; AMDP - Use; AMDP - Client Handling; AMDP - Macros; AMDP - Exception Classes; AMDP - Glossary; AMDP - Examples; Currently, AMDP only supports database procedures and functions from the SAP HANA an AMDP method that implements an SQLScript procedure cannot call any database procedures or use any database functions that themselves use the AMDP procedure or function. Now let’s In this post, you will learn to use SQL Script in AMDP for. An excerpt from the 2nd edition of my book " SQLScript for SAP HANA ", published by Rheinwerkverlag, SAP Press. Hinweise Für die Bearbeitung von Datenbankprozeduren und -funktionen in AMDP-Methoden sind die ABAP Development Tools (ADT) besser geeignet als der Class Builder der ABAP Workbench . Additionally, the client handling is adjusted for the AMDP methods by including appropriate additions in the AMDP method declaration part. This means that AMDP classes can only be The implementation of an AMDP method is saved to the ABAP database schema by the ABAP runtime environment. bmsbxurx drizlu wnvaa ochry veauqw gsqc efdkqr hhkun iqopudz cntkyvlt jki cok kbyonow xnqhmcy ddpxjr
