Thank you Naomi, Mike and Srdjan. I think is too much work to do a simple thing like that. Anyway ...Im going to choose using fake data group control. Im going to eliminate the report header and the report footer and Im going to use the header group and the footer group instead. Also Im going to prestablish the number of the detail lines.

Thank you all for your help

Best Regards
