hi,

May be with the same key fields values a record already exist in the table. Please check.

What do you mean. I only see wa_master in your code, so from your code it is only possible to update or modify one record.

Also modify statement already takes care of this. If key exists it will update the record and if it does not exist it will insert.

So your code could also be written as follows and would do the same thing:

CASE ok_code.

    WHEN 'SAVE' or 'UPDATE'.

      MODIFY  zcust_master FROM wa_master.

      IF sy-subrc EQ 0.

        MESSAGE 'Saved Sucessfully' TYPE 'S'.

      ELSE.
        MESSAGE 'Not Saved' TYPE 'E'.

      ENDIF.

      CLEAR wa_master.

ENDCASE.
