Populating a Listbox from another Listbox selection

[Former Member]

I have a requirement to have 5 list boxes on a screen.

The first one is populated by some values which I have done using fcn mod VRM_SET_VALUES.

When a selection is made from this list box the requirement is to populate the second listbox with relevant values to the selection made in the first list box.

How can this be done because the selection does not trigger a PBO event?

Many Thanks In Advance for any advice.

I guess you have to use the Function

DYNP_VALUES_UPDATE.

sEE THE EXAMPLE GIVEN IN THE DOCUMENTATION TO KNOW HOW TO USE IT.

Hi David,

You can use the Function module <b>DYNPRO_VALUE_READ</b> , for reading the value in first list box to populate the values in the secondlist box and so on.

Hope this helps.

Hi david,

1. Define the listbox (1st listbox)

as

PARAMETERS : EVTTYPE AS LISTBOX VISIBLE LENGTH 20

<b>user-command mycom.</b>

2. User command extension is important

(bcos then only it will trigger pbo)

3. Afterwards u can use the

event at selection-screen

or at selection-screen output

to populate the 2nd/related list box.

If u r working with screen, assign Function code for the list box. It will automatically call the PAI & PBO.

Elseif u r working with selection screen, write the code in AT SELECTION-SCREEN OUTPUT.
