query regarding drop down list box..

[Former Member]

Hi All,

I have drop down list box on the my screen.

I have assigned function code to this list box.

Lets say there are 5 entries in the drop down list box

Now whenever i clicks on this list box it drops down to show all 5 entries.

If i selects one among them,it gets selected.

But when next time i clicks on drop down list,previously selected entry gets added int the list,that means it shows 6 entries.

Every time it shows 6 entries,that means 5 entries + one entry which is previously seleted.

But if i remove function code assigned to this drop down list,it works fine.

Can anybody suggest me,why is it happening so.and the solution for that?

Hi Sanjay,

clear the field <value> when u call the VRM_SET_VALUES FM.

because when the fcode is executed,again the PBO is getting executed that is why your getting the selected value again in the drop down list.

Hi,

Thanks for your reply.

But i could not understand you clearly.

I am using 'F4IF_INT_TABLE_VALUE_REQUEST' to fill the F4 help.

where 'T_HEADER-PO_SUPPLEM' is my field to which i have given drop down.

and r_po_supplem is the range which contains all input values.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'LOW'

dynpprog = sy-repid

dynpnr = '1000'

dynprofield = 'T_HEADER-PO_SUPPLEM'

value_org = 'S'

TABLES

value_tab = r_po_supplem.

In your statment u have mentioned to clear <b>field <value></b> but i did not understand that..

can you please explain it?

I meant always clear the values(field) which you are building in the drop down list table.since the after executitng the fcode it goes to pbo again.

Checck the code after below my prvious post
