Custom Screen Validation

Former Member — Thu, 27 Jan 2011 14:12:59 GMT

I am trying to change HR infotype screen.

I have added a custom listbox which has 10 entries.

What I want to do is as soon as any entry in the list is chosen by

using the mouse cursor I want to be able to execute some custom code.

At the moment this only happens when I press the 'Enter' Key.

Does anybody know if this event I am trying to capture does exist.

i.e. as soon as an entry in a list box is chosen without the need

to press the enter key

Any help would be much appreciated

Thanks

Andy

Andy, I think list box is one of the controls that support an OK Code. So, you can write your code under the PAI for your specific OK code for the list box.

Hi Andy,

Use "USER-COMMAND uc" addition in PARAMETERS statement for your listbox. I am able to display the popup with different messages as soon as user selects a value from the Listbox. There is no need to hit 'Enter' key.

REPORT ytest.

TYPE-POOLS: vrm.

DATA: name TYPE vrm_id,

list TYPE vrm_values,

value LIKE LINE OF list.

PARAMETERS: ps_parm AS LISTBOX VISIBLE LENGTH 10 USER-COMMAND uc.

AT SELECTION-SCREEN OUTPUT.

name = 'PS_PARM'.

value-key = '1'.

value-text = 'LINE 1'.

APPEND value TO list.

value-key = '2'.

value-text = 'LINE 2'.

APPEND value TO list.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = name

values = list.

CLEAR value.

REFRESH list[].

AT SELECTION-SCREEN.

LOOP AT SCREEN.

IF ps_parm EQ '1'.

CALL FUNCTION 'POPUP_TO_INFORM'

EXPORTING

titel = 'Test'

txt1 = 'Listbox'

txt2 = '1'.

ELSEIF ps_parm EQ '2'.

CALL FUNCTION 'POPUP_TO_INFORM'

EXPORTING

titel = 'Test'

txt1 = 'Listbox'

txt2 = '2'.

ENDIF.

ENDLOOP.

Hi Scott,

Yes the addition User command should works perfect for you requirment. I used in one of my code and it works with no glitch. I have posted the same for your reference.

SELECTION-SCREEN: SKIP 1.

p_apath(150) TYPE c AS LISTBOX VISIBLE LENGTH 132,

p_afile(132) TYPE c.

SELECTION-SCREEN: END OF BLOCK b2.

SELECTION-SCREEN: BEGIN OF BLOCK b3 WITH FRAME TITLE text-003.

PARAMETERS : p_opath(132) TYPE c," DEFAULT 'C:\Documents and Settings\Error.txt' ,

Hi Andy,

You need to set the Function code (FctCode) for the custom list box field during screen design.

For example for the list box field give the value 'SET' in the FctCode.

Write the coding in PAI which is triggered if you select any value in the list box.

MODULE USER_COMMAND_1000 INPUT.

case sy-ucomm.

when 'SET'.

endcase.

Srini.
