Transfer Order Collective Form

Question

Hi All,
I am working on TO Collective form. This form has a delivery number in it. But my requirement is they need the last 3 digits of the Delivery Number to be printed in a bigger font beside the company logo.
I have written the following code in the subroutine.
FORM LAST_3 TABLES int_inval  STRUCTURE itcsy int_outval STRUCTURE itcsy.
DATA: w_nlpla type ltap-nlpla.
Read input table for Input parameter
  READ TABLE int_inval  with key name = 'LTAP-NLPLA'                .
  check sy-subrc  eq 0                             .
    SHIFT int_inval-value left deleting leading space.
    w_nlpla = int_inval-value.
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      INPUT         = w_nlpla
   IMPORTING
     OUTPUT        = w_nlpla
  READ TABLE int_outval index 1.
    int_outval-value = w_nlpla+7(3).
    modify int_outval index 1.
ENDFORM.
and in the change editor of form layout.
DEFINE &LAST_3& = ' '.
PERFORM LAST_3 IN PROGRAM ZMSPERFORMS_TRANSFER_ORDER
USING &LTAP-NLPLA&
CHANGING &LAST_3&
ENDPERFORM
I am not able to get the last 3 digits of delivery number printed.

Answer 1

Try adding the same subroutine in a report program instead of a subroutine pool..And try to print the form..
The sap help uses report program for storing the subroutine..
