Data Doubling in the Cube

Dear Experts

When I am running Account Based Calculation through Data Manager Package, transaction data in the cube is double. Hence my end reports are wrong.

I run the optimization package and no change in the data. I also checked the Business rule to make sure none of the rule make the system to do doubling the data.

The logic is not set up as default logic.

I am experiencing the problem when I run it for period 2, it is OK with period 1.

How can I solve the problem.

My model is YTD in BPC NW 10.

Kind Regards

Abraham
