Calling a std user exit from a user defined user exit

Question

hi
I have a standard User Exit. I want to call it from a User Exit created by me something like zaaabbbb.
Can you please tell me the procedure how to do it ?

Hi,
If the user exit is a Z include in a function module then you can call the function module like any other function module passing the required parameters. For example CALL CUSTOMER-FUNCTION '002' in transaction VA01 corresponds to function module EXIT_SAPMV45A_002. You can call this function module like you do any other function module.
CALL FUNCTION 'EXIT_SAPMV45A_002'
  EXPORTING
    i_tvak        =
    i_tvta        =
    i_vkgrp       =
    i_vkbur       =
* IMPORTING
*   E_KUNNR       =
If the user exit is a subroutine in an include in SAP name space (For example subroutine userexit_delete_document in include mv45afzz), then find out the main program in which the include is included (for example mv45afzz is included in program sapmv45a). Once you have done that you can using the following statement to call the subroutine.
PERFORM <subroutine name> IN PROGRAM <program name>.
For Examaple
PERFORM userexit_delete_document IN PROGRAM sapmv45a.
Please make sure that you use the main program name (In our example sapmv45a) and not the include name (in our example mv45afzz).
