list box at selection screen

Former Member — Mon, 13 Apr 2009 13:23:29 GMT

Hi guys,

I have created report:

TYPE-POOLS: vrm.

DATA: name TYPE vrm_id,

lista TYPE vrm_values,

value LIKE LINE OF lista.

PARAMETERS: SVRHA(10) AS LISTBOX VISIBLE LENGTH 30.

AT SELECTION-SCREEN OUTPUT.

name = 'SVR'.

value-key = '1'.

value-text = 'Text 1'.

APPEND value TO lista.

value-key = '2'.

value-text = 'Text 2''.

APPEND value TO lista.

...3,4,5,6,7,8

value-key = '9'.

value-text = 'Text 9'.

APPEND value TO lista.

value-key = '10'.

value-text = 'Text 10'.

APPEND value TO lista.

value-key = '11'.

value-text = 'Text 11'.

APPEND value TO lista.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING id = name

values = lista.

START-OF-SELECTION.

IF........

WRITE: / 'Parameter:', SVR.

1. In display list on screen 'Text 10' and 'Text 11' come after 'Text 1', how can I put it in order after

'Text 9' ?

2. How I write conditions in start of selection, using value key or value text ?

Thanks,

Nihad

1) Use a leading zero for values that are 1-9.

value-key = '01'.
value-text = 'Text 1'.
APPEND value TO lista.
value-key = '02'.
value-text = 'Text 2''.
APPEND value TO lista.
...03,04,05,06,07,08
value-key = '09'.
value-text = 'Text 9'.
APPEND value TO lista.

2) the NAME field should hold the value of the parameter called SVRHA.

name = 'SVRHA'.

so when you want to write the value, just write out the SVRHA field.

Write:/ SVRHA.

This will hold the key value of the selected item in the listbox.

Ok , I missed while typing it shoud be SVRHA not SVR, thanks. What about conditions? Is this ok for example:

data: begin of itab occurs 0,

field type c,

.........

end of itab.

IF SVRHA = '01'.

itab-field = 'Text 1'.

endif.

IF SVRHA = '02'.

itab-field = 'Text 2'.

endif.

etc.

I would suggest using a CASE statement.

CASE SVRHA.
  when '01'.
     itab-field = 'Text 1'.
  when '02'.
    itab-field = 'Text 2'. 
ENDCASE.

Hi Nihad,

Yes, You can simply check with SVRHA. It will hold the value whichever you selected in the screen.

And also, normally the sequence is defined by KEY value itself. When I try the same thing which you gave in the screen, I could see all the values in proper sequence.

Hi guys, I have very strange situation. When I run transaction my listbox have these values:

01 Proba

02 Test

03 Izvodi

04 Kreni

when I enter any other field on screen and press enter I got these values in listbox:

01 Proba

02 Test

03 Izvodi

04 Kreni

if I press enter again I got new line of values in listbox and it looks like this:

01 Proba

02 Test

03 Izvodi

04 Kreni

Each press on enter adds new line in my listbox, What should I do, why is this happening?

you need to refresh/clear the internal table before you populate the table. Because you are not using any clear it is adding the duplicates.

Hello Nihad,

A bit of magic will do )

CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING
      id     = name
      values = lista.

  REFRESH lista. "Ad this line

Try to figure out why this helped )

BR,
