BADI

BADI - Business ADD-INS


    *  BADIs are used to adding some additional functionality to standard functionality without disturbing the standard functionality. 

    *  BADIs are introduced from 4.6C version onwards. BADI contains 2 sections.

            1. BADI Definition - SE18

            2. BADI Implementation - SE19

    * Badi Definition: - 

            > Each BADI definition contains one adapter class and interface. 

            > Adapter class taking care the version change management (Whenever the version is changed if any changes required in the BADI those are done by adapter class).

            > Interface is the collection of methods which are defined not implemented. 

            > Those are implemented through BADI implementation based on client requirement.

    * BADI Implementation: -

            > BADI Implementation is nothing but implementing the methods which are                             defined in BADI definition.


    Types of BADI’S

        There are 4 types of BADI‟s

            1. Single Implementation BADI

            2. Multiple implementation BADI

            3. Filter BADI

            4. Custom BADI.

            1. Single implementation BADI:

                *  This BADI can allow implementing only once. 

                *  This type of BADIS is called single implementation BADI.

                *  If the BADI definition does not contain 'multiple use' check box.

                * Then the BADI is called as single implementation BADI.

          2. Multiple implementation BADI:

            *  It can allow implementing the same BADI any number of times.

            *  If the BADI Definition contains 'multiple use' check boxes 

            *  Then the BADI is called as Multiple Implementation BADI.

        3. Custom Badi:

            *  These are created by us (Technical people)

        4. Filter Badi:

            *   It is type of BADI which has a filter value 

                    so that only those implementations which satisfy the filter value are executed. 

            *  The remaining implementations are not executed 

                    this type of BADI is called a filter BADI.

            *  Filter Badi is used to implement the same BADI multiple times with different                             conditions. 

            *  If we want to implement the BADI based on country specific then we go for filter                     BADI.

Custom entity/Action dialog in RAP using Unmanaged scenario

Image
A custom action is like a button (e.g., Approve , Submit ) shown in the Fiori app. A dialog is a popup where the user can enter some input before performing the action.                    Refer:-  Determination + Side effects(On Modify) in RAP Unmanaged                    Refer:-  Determination + Side effects (On Save) in RAP Unmanaged Step 1:   Create behavior definition for abstract entity.          * Right click on Core data service - New - data definition.          * Give name and description.          * Click on Next.          * Select Abstract entity with parameters and click on finish. @EndUserText.label: 'Abstart entity for status field' @Metadata.allowExtensions: true define abstract entity ZA_AB_STUH_13 //with parameters parameter_name : paramet...

New syntax for append- VALUE (new syntax 7.4+) in ABAP

Image
* We use APPEND statement to insert the records at the last of the internal table. * In SAP ABAP new syntax, we can use VALUE expression instead of APPEND statement. * Value expression is a powerful mechanism to declare as well as initialize the internal tables. * It is a powerful utility where we can achieve the result with minimal coding. * Value expression is of 2 types.      -  Define the type before using it with VALUE keyword. The type defined is structure type  or table type.      -  Using # character for type and use it with VALUE keyword. Report REPORT  zab_rp_append_value . TYPES :  BEGIN  OF  ls_stu ,          st_id ( 10 )    TYPE  n ,          st_name ( 15 )  TYPE  c ,         END  OF  ls_stu . DATA :  lt_stu  TYPE  TABLE...

Read statement new syntax in ABAP. (7.4+).

Image
*  Before ABAP 7.4, we used READ TABLE statement to read the first matching record from the internal table  based upon key or index . * In SAP ABAP new syntax, instead of READ TABLE , we can use the table expressions. * We need to use the square bracket [ ], In the square bracket, we need to specify the key or index. * While using table expression, If the table entry does not exist, system throws the exception CX_SY_ITAB_LINE_NOT_FOUND. * Use line_exists statement to check the existence of a record. Report REPORT  zab_rp_read_new . TABLES :   vbak . SELECT-OPTIONS :   s_vbeln  FOR  vbak - vbeln . SELECT  vbeln , erdat , erzet , ernam , auart         FROM  vbak         INTO  TABLE  @DATA ( lt_vbak )          WHERE  vbeln  IN  @s_vbeln . WRITE :   'Index value'  COLOR  5 . READ  T...
