Hi,

In the form you have to call subroutine as follows.

/: Perform sub in program Ztest

/: using &field_check&

/: changing &return_value&

/:endperform.

in the subroutine program you have to code as follows.

Form sub tables intab structure itcsy

outtab structure itcsy.

read table intab with key name = 'FIELD_CHECK'.

if sy-subrc = 0.

check input-value = 'TRUE VALUE'.

read table outtab with key name = 'RETURN VALUE'.

if sy-subrc = 0.

outtab-value = 'RETURN VALUE'.

outtab-name = 'RETURN VALUE'.

modify outtab index sy-tabix.

endif.

endif.

why dont you use using and changing parameters?

On false condition, pass some variable back to the form, so it will continue execution just after the perform..

IT WORKS SIMILAR TO CALL-BY-RFERENCE.THE VALUES RETURNED WILL BE SAME FOR FORM AND PERFORM.

****************************SUB-ROUTINE USING CHANGING VALUE****************************

DATA : A TYPE I VALUE 10.

PERFORM SUB CHANGING A.

WRITE : A.

PARAMETERS USED IN THE CALLING SUB-ROUTINES ARE CALLED ACTUAL PARAMETERS.

PARAMETRS USED IN THE CALLED SUB-ROUTINES ARE CALLED FORMAL PARAMETERS.

CALL-BY-REFERNCE:
