more than one database driver has been used

Hi all,

I have a report where two database drivers have been used. one is a ado.net(xml) and the other one is epicor. I want to add a table from epicor 905, when i am trying to change then the popup comes saying more than one database driver has been used in this report.if you want to make any changes use database/set location.Please make sure that no SQL expression is added and no server side group by is performed.

how should i go ahead to make changes. please suggest !!!

Regards,

Ali
