Hyperlink with Bex Variables

Hi,

I try to create a hyperlink between 2 webis. It works fine if the prompt of the target webi have been created in the webi query panel. but if the target webi query contains Bex variables (define in query designer), then I receive an error message (WIS 10901).

I read some posts on the forum on this subject but never found the solution. I tried to send the key, to use the function URLEncode... but nothing worked!

Any idea would be much appreciated.
