'Enter' button event

[Former Member]

Let's say I've got on my selection screen

PARAMETERS: werks LIKE t001w-werks.

I'd like the programm after writing the werks and pressing enter button to check some condition. If werks meets some condition then I'd like to modify my selection screen (add one more PARAMETERS below the werks). How to do this simply? Greetings. P.

Hi,

Try this:

At selection-screen.

if werks <> '1000'.

message E001. "Plant is not 1000

endif.

[Former Member]

Hi,

data: gt_vbap type standard table of vbap.

parameters p_vbeln type vbak-vbeln.

at selection-screen output.

if p_vbeln is not initial.

select * into table gt_vbap from vbap where vbeln = p_vbeln.

endif.

reward points if useful,

Hello P,

This is what you want.

PARAMETERS: BUKRS LIKE EKKO-BUKRS MODIF ID BUK.

AT SELECTION-SCREEN OUTPUT.

IF WERKS IS INITIAL.

LOOP AT SCREEN.

IF SCREEN-GROUP1 = 'BUK'.

SCREEN-ACTIVE = 0.

SCREEN-INPUT = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ELSE.

SELECT SINGLE * FROM T001W WHERE WERKS = WERKS.

IF SY-SUBRC = 0.

LOOP AT SCREEN.

IF SCREEN-GROUP1 = 'BUK'.

SCREEN-INVISIBLE = 0.

SCREEN-INPUT = 1.

SCREEN-ACTIVE = 1.

MODIFY SCREEN.
