Insert * to a variable in request page report with table relation G/L Account

Hi experts. I have an issue at the reports. I am using NAV 2015. I have created a report. At the request page i created a variable and insert at the properties the table relation to G/L Account.

My issue is that i cannot use the (*) eg. 12-00* in this field. At the original field of the GL Account section i can. I need the same for the request page.

Any help please.
