Hi,
have treid with BEx query designer if not please start now.
open the query designer -> you can restrict the values based on the 0INFOPROV KF1, KF2 and KF3 in InfoCube 1 and KF4, KF5 and KF6 in InfoCube 2.
but you want dispaly the vlaues for all key figure values both cubes have same records (ex- material/customer/plant.. etc)
otherwise it will give some of the key figure values was blank.
Thanks,
phani.
