Hi,

Set the screen attribute to screen-active = 1 for the select-option fields. Try like this



select-options: s_input for mara-matnr MODIF INP.

after validation of the parameter.
if sy-subrc NE 0.
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
IF screen-group1 = 'INP'.
screen-active = 1.
screen-input = 1.
screen-output = 1.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
endif.

Regards,

Vik

Hello Sreedhar,

I think for validation you have used AT SELECTION-SCREEN ON <param> because of which your selection-screen is behaving this way.

If you DONOT want this behaviour, then change the event to AT SELECTION-SCREEN. This should suffice.

Hope i am clear.

- Put the parameters/select-options in a [SELECTION-SCREEN BLOCK|http://help.sap.com/abapdocu/en/ABAPSELECTION-SCREEN_BLOCK.htm].

- Execute you check in a [AT SELECTION-SCREEN|http://help.sap.com/abapdocu/en/ABAPAT_SELECTION-SCREEN.htm] [ON BLOCK|http://help.sap.com/abapdocu/en/ABAPAT_SELECTION-SCREEN_EVENTS.htm#!ABAP_ALTERNATIVE_4@4@] blo.

When the error will be sent, the whole block keeps editable and the cursor is at the first field of the block.

Regards,

Raymond

parameters p1 type matnr obligatory.

select-options s1 for mara-matnr.

selection-screen end of block b1.

at selection-screen on block b1.

if p1 ne '123'.

message e000 with 'Error'.

endif.
