Bex variable and BOBJ LOV

Hi All,

We have a  BOBJ 4.1 SP04 Crystal Enterprise report on top of BW Bex query.

The Bex variable prompts in BOBJ and shows both key and text in list of values (key - text).

Even after changing settings in Bex to display only key values it is displaying like key - key.

Is there any settings in BW or Bex to display just key values in BOBJ list of values.
