Pattern search using Bex parameter in Crystal

How to get the results using a Bex query filter for Pattern search with Crystal.

While pattern search works fine with the variable defined in Bex analyzer but when I attach it to a Crystal report, it doesnt seem to work.

Bex variable has input like "IBM*", which works fine with Bex analyzer but the same input via Crystal doesnt fetch data.

Thanks in advance,
