关于BP的badi

For BP updates at create/change save time, the BUPA_*_UPDATE BADIs need to be used. The interface only provides the GUID of the not yet created BP or the GUID of the changed BP, not a bunch of parameters that you can change before save. However, you can call the BUPA_*_CALLBACK series of function modules to get the info you need about the BP, and use a field symbol to directly access the data in the memory stack i.e., (SAPLBUD0)MEM_BUT000[] and change the values. I am using this technique to add an authorization group to certain BP type at create save time. 

BADI:PARTNER_UPDATE 综合了BUPA_*_UPDATE BADIs ，并且使用FM：BUPA_*_CALLBACK获得相关数据

 

 

 

 

I figured out another way to do this.

  FIELD-SYMBOLS TYPE ANY TABLE.  

DATA : ws_bus000_i TYPE bus000___i.  

FIELD-SYMBOLS TYPE bus000___i.  

IF sy-tcode = 'BP'.

     ASSIGN ('(SAPLBUD0)MEM_BUT000[]') TO .

     IF IS ASSIGNED.

       LOOP AT  ASSIGNING .

         IF IS ASSIGNED.

           IF -partner_guid = ws_but000-partner_guid.

             -bu_sort1 = 'BP'.

           ENDIF.

         ENDIF.

       ENDLOOP.

     ENDIF.

     UNASSIGN : , .

   ELSEIF sy-tcode IS INITIAL.

     ASSIGN ('(SAPLBUD_MEM)gt_but000_mem[]') TO .

     IF IS ASSIGNED.

       LOOP AT  ASSIGNING .

         IF IS ASSIGNED.

           IF -partner_guid = ws_but000-partner_guid.

             -bu_sort1 = 'WEB UI'.

           ENDIF.

         ENDIF.

       ENDLOOP.

     ENDIF.

     UNASSIGN : , .

   ENDIF.

on debugging I could figure out the program containing the data in the memory.

Before the save I accessed this program and updated the parameter as required.

Also For transaction BP this program is not available but there is another program so there is an if else based on the sy-tcode.

I need to check for other BP transactions as well but as of now this seems good.
