go to se18.

Select BADI Name.

and give the name as ME_PROCESS_REQ_CUST

click on display

From menu click on -> implementation -> create

give the implementation name as

ZME_PROCESS_REQ_CUST

Give a short text selecting describing the implementation.

Click on the interface tab.

click on the process_item method

and write the following code.

  DATA: st_eban TYPE mereq_item.

  st_eban = im_item->get_data( ).

IF st_eban-bnfpo IS INITIAL.
  MESSAGE 'Enter PR Number' TYPE 'E'.
ENDIF.
