Badi

BADI


        *  Badi - business add ins.

         *   Custom enhancements to sap functionality.

        *   Enhancement means add functionality to existing function without changing the structure

        *  Badi are implementing using oops technique.

        *   Badi is nothing but an interface.

        *  Each badi consists of the method without implementation called badi definition.

        *  We need to create classes to write the abap code by implementing the methods called Badi implementation.


se18 -- Create Badi definition.

se19 -- Badi implementation.


Steps to create a Badi.

    *   Goto SE18 create enhancement spot and give short description and select package.

            



    *  Then click on create Badi and give name and short description.

                



    *  Goto Interface tab and give interface name.

                    



    *  Give name and double click on interface name then asks to create interface.

    *  Give methods.

                


    * Save and activate and go back to data definition.

     *  Right click on implementation select 'create Badi implementation' and give name and short description for enhancement implementation.

     *  Then give Badi implementation name and short description and class name. Class name automatically created when you start with z.


    *  Then click on implementing class and double click on methods to create implementation and write implementation.

        



        

       * Save and check and activate likewise to implement all methods.

            



  Calling Badi in SE38

        REPORT ZAJAY_BADI_DEMO.

    data obj type REF TO ZAJAY_BADI_DEF_DEMO.
    get badi obj.
    call badi obj->add.
    call badi obj->sub.

   Output:

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...
