Getting selected value from Listbox

[Former Member]

Hi,

I have populated my listbox on the selection screen using the function module VRM_SET_VALUES.

How do I get the value which is selected from the list box.

Where is the selected value in the listbox stored.

Thanks,

Abhishek

Hi

there will be a screen field associated with list box rite, that screen field will hold the selected value from drop down

[Former Member]

The screen field doesn't hold any value for the selected field. It is blank.

[Former Member]

can u copy paste the code used to call FM- VRM_SET_VALUES

[Former Member]

The code I used is:

Another issue is that whenever I select any value in the listbox it is not displayed on the screen. It becomes blank again.

PARAMETERS: p_prin AS LISTBOX VISIBLE LENGTH 30 USER-COMMAND sele.

DATA: i_printers TYPE STANDARD TABLE OF frprlist,

wa_printers TYPE frprlist.

DATA: l_name TYPE vrm_id,

i_list TYPE vrm_values,

l_ctr TYPE i VALUE 0,

wa_value LIKE LINE OF i_list.

CLEAR: wa_value.

• Get printers

CALL FUNCTION 'RSPO_FRONTEND_PRINTERS_FOR_DEV'

EXPORTING

device = p_print

TABLES

list = i_printers

EXCEPTIONS

no_list = 1

list_truncated = 2

name_not_found = 3

OTHERS = 4.

IF sy-subrc EQ 0.

• Populate to drop down box

l_name = c_prin.

LOOP AT i_printers INTO wa_printers.

l_ctr = l_ctr + 1.

wa_value-key = l_ctr.

wa_value-text = wa_printers-prname.

APPEND wa_value TO i_list.

CLEAR wa_value.

ENDLOOP.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = l_name

values = i_list

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

IF sy-subrc NE 0.

• Do nothing

ENDIF.

ENDIF.

CLEAR: l_name, l_ctr, wa_value, i_list.

pass

l_name = p_prin

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = l_name

[naimesh_patel]

ID parameter of the FM VRM_SET_VALUES should contain the name of the field on which you have created list box.

Like:

l_name = 'P_PRIN'.

Hi.

I have several list box on my screen without any problem, except that I don't know how to get the selected value from list box (the name of this post)

When I select a value from the list box, what I get it's the value-key, and I need the value-text... How can I get it?

For example:

CLEAR values2.

value2-key = '1'.

value2-text = 'E'.

APPEND value2 TO values2.

value2-key = '2'.

value2-text = 'S'.

APPEND value2 TO values2.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'TBI_DIRECCION_TEM-DS_ORIENT_VIA'

values = values2.

In the program, when I need to get the value, I've found that the field TBI_DIRECCION_TEM-DS_ORIENT_VIA has the value '2' (corresponding to the value-key), and not 'S' (corresponding to the value-text, that's what I need)

How can I get it?

Thanks in advance.

Hi Carolina,

Hearty welcome to SDN.

Please go through the site fully so that you can have better idea on how much SDN can help you. Please do give some time to search for some time in SDN before posting any query. Hope you follow from now.

Make the changes in the code as i have shown..

CLEAR values2.

value2-key = 'E'.

value2-text = '1'.

APPEND value2 TO values2.

value2-key = 'S'.

value2-text = '2'.

APPEND value2 TO values2.

Cheers!!

Thanks Balu for your advice.

And I guess, I didn't explain myself clearly...

My problem wasn't that I couldn't show the appropiate value on the screen. I needed to show 'S' or 'N', but when I was working with the value selected (S or N), in the field was stored 1 or 2, and I needed the S or N.

But you gave me a good idea (and that was a doubt I had). I changed the code for something like this:

CLEAR values2.

value2-key = 'N'.

value2-text = 'N'.

APPEND value2 TO values2.

value2-key = 'S'.

value2-text = 'S'.

APPEND value2 TO values2.

I'm using value-key to store also the value-text, and when I read the value selected I get the S or the N.

So, thanks very much 😃 I learned so much with the posts that I've found at the SDN.
