Date as KF in report, and Cube cannot be compressed

Hello All,

Q:

1. I have a report where the Date is used as a Key Figure, and also at the CUBE.

2. Now on deltas all other Key Figure are negated but not the date Key Figure.

3. This doesn't allows me to perform compression for obvious reasons of date as KF.

We face enough performance issues due to complexity of the report and huge no. of records at CUBE, Would appreciate any responses to achieve compression with zero elimination.

I have tried few solutions including formula variable with replacement path- but this requires the base object to be in the result set. Also tried to populate date as DEC(Number) in database and use function process value as date, however it aggregates the values and then convert to date which is sometime 'X' for exceeding the limit.

Also tried with different aggregations of SUM and MAX at info object, doesn't works .

Please post your ideas.

Thanks,

TA
