Linking Documents in Webi for two reports from Bex based on GL account

Hi,

I am trying to link two documents based on GL account( infoobject having attributes) created from bex query and used in webi by using BICS connection.

when I m using GL account as a prompt in the destination report then it is not displaying all the list of values as shown in screenshot 1.

I gave the sleection criteria as * and proceeded but  when I did the linkking and tried to run the report I got the error as in screenshot 2.

Please provide your valuable inputs and help solve the problem.

NOte:If i m using a normal object then i m able to link properly
