Listbox after selection, no value

Hi All,

I am using ABAP Listbox with VRM to set the dropdown.

I am able to set the dropdown, but the user selected value doesnot appear in the parameter specified.

I have tried using VRM_GET_VALUES but the same didnt work.

Please guide.

Below is my code:

REPORT zbw_mosl_file_upd.

TYPE-POOLS: vrm, slis.

/bic/zcretalr TYPE /bic/oizcretalr,

END OF ty_retailer.
