[gurralakrishna]

Hello All,

Currently I am working on cognos upgrade project. this upgradation from 7 to 10.2.1 cubes.we are facing some issues with measures.
some times it is getting XSUM issues.at that time we are changing usage property from fact to attribute.
is it right way?

Also where we need to modify for improving query performance in FM Model.

Here we are replacing IQD's with packages.

Regards,
Krishna.
