Module - pool Question..?

Question

Hi,
The select-option functionality is not working in the Module pool...
SELECTION-SCREEN BEGIN OF SCREEN 1030 AS SUBSCREEN.
SELECTION-SCREEN BEGIN OF BLOCK b4 WITH FRAME TITLE text-003.
SELECT-OPTIONS: o_ledger FOR zsfiglscr_chead-nrldnr .
SELECTION-SCREEN END OF BLOCK b4.
SELECTION-SCREEN END OF SCREEN 1030
Then we are calling that selection screen in sub-screen  area. For that the developers have written following code in the PBO of module pool screen.
CALL SUBSCREEN sub1 INCLUDING 'SAPMZFIGL_ALLOCATION'  v_dynnr.
Now the select options functionality is not working...i chked the field zsfiglscr_chead-nrldnr and it has a search help attached to the data element...what can be the reason...please provide some inputs...
Cheers:Sam

I've tried various combinations and they all work in an ECC system... can you try the report below out in your system and check which of the 3 options used work and don't work for that F4 help (you'll need to create a screen 9999 as described in the sample code:
report zlocal_jc_sdn_query1.
tables:
  bpvc,  "a structure with rldnr in it
  t881.  "Ledger Master
data:
  g_char2(2)            type c,
  g_dynnr               like sy-dynnr.
