Adding description in variable screen of Bex query

Hi All,

I have restricted one variable ( let us say abc)

these variable have value P, A.

when user select this value in the variable screen (let us say 'P') then the description field also shows 'P' .

I want user to select the value as 'P' but in description field it should come as "Pending' .

Please suggest how to do that

regards
