parameter selection

[Former Member]

Hi,

I have a select-option s1 and the parameter p1.

if select -option s1 is blank , then the parameter p1 needs to be optional, else if select-option s1 has some values ,then the parameter p1 needs to be obligatory.

how do i specify this conditions?

Any help is rewarded.

hi Gautam,

AT SELECTION-SCREEN.

IF s1 IS NOT INITIAL AND p1 IS INITIAL.

==> issue some message here that p1 has to bi filled.

ENDIF.

hope this helps

I think it should be under AT SELECTION-SCREEN, since you want to check the user input at PAI, not PBO.

IF matnr IS INITIAL.

IF mtart IS INITIAL.

f = 1.

ENDIF.

ENDIF.

START-OF-SELECTION.

IF f <> 1.

WRITE:/ matnr.

Hi,

do like this.

At selection-screen on S1.

If not s1 is initial.

message 'Enter value for p1'.

leave list-processing.

endif.
