Selection screen fields hiding?

[Former Member]

Hi,

In executable program,

I have 3 fields in selection screen. But initially I need to display only 1 field, after entering the value for the first field, I need to check that value and if its correct then user should get the left of the 2 fields to enter the input values. After entering the 2 fields’ values and click submit button program should execute.

Can any one tell me what the best way I can do this ?

Initially I put one field in selection screen and I used CALL SELECTION-SCREEN statement for the 2 fields, but for this after entering the 2 fields values and submit program is not executing the

‘START-OF-SELECTION’ logic, it’s simply coming out from START-OF-SELECTION line.

Thanks for ur time.

At INITIALIZATION event Hide the two fields using LOOP AT SCREEN.And modify the screen.

In AT SELECTION-SCREEN event loop through the screen again and validate the value entered and do the same logic to modify the screen

[RichHeilman]

Loop at the screen and set them off in the AT SELECTION-SCREEN OUTPUT event. Here is an example program. If the first field has a value, then the second and third fields will be opened.

report zrich_0002.

parameters: p_field1 type c,
            p_field2 type c modif id chk,
            p_field3 type c modif id chk.


at selection-screen output.

  if p_field1 is initial.

    loop at screen.
      if screen-group1 = 'CHK'.
        screen-active    = '0'.
        modify screen.
      endif.
    endloop.

  endif.

Hi

Use Submit Keyword for passing data in between two executable programs. Refer to its documentation.

Hi Kavitha,

Solution to your second problem:

Just change the user-command code for the Submit pushbutton as 'ONLI'.

FYI

When you click the second submit button, you will not be able to trigger the start-of-selection event if the id is not 'ONLI'. Thats' the reason, after you click the submit button AT SELECTION-SCREEN OUTPUT event will be triggered.

You can trigger START-OF-SELECTION Event only by using the F8 key or the execute button.

Just change the user-command code for the Submit pushbutton as 'ONLI'.

Check the below logic..

Report = Zreport.

1.Define the parameters as p1, p2, p3 and pexecute.

where pexecute as no-display default to 0.

2.In the INITIALIZATION even make the parameters p2 and p3 invisible.

3.At selection-screen event..validate p1 and if correct, enable p2 and p3.

4.In start of selection event use the below code.

if pexecute = 0.

submit zreport with (submit the same abap_)

p1 = p1

p2 = p2

p3 = p3

pexecute = 1.

else.

--> your processing logic.

endif.
