User Exit for VF02 (Change Billing Document)

[Former Member]

In transaction VF02, when i go to maintain the header text, if i do not maintain the header text , then at the time of saving the document i want to fire the exit so that the header text is always maintained. How do i do it for Header text.

Hi!

Use the program: RV60AFZZ

FORM USEREXIT_NUMBER_RANGE USING US_RANGE_INTERN.
if sy-tcode = 'VF02' and   "Invoice change transaction ?
   sy-ucomm = 'SICH'.   "Save operation ?

* here you have to use READ_TEXT fm with 
* object: VBBK
* ID: 0001 (maybe other if the text is in an another object)
* language: sy-langu
* name: vbrk-vbeln

* if the text does not exists, then create an message with SE91 (with name ZSD_ERROR) 
* and then use the statement:
MESSAGE E001(ZSD_ERROR).   "this will prevent saving

endif.
endif.
ENDFORM.
