Reconciliation of data between BPC and BW Cube

Hi,

We need to run a reconciliation process between BW Cube data and BPC Cube data. What would be the best practice to do so.

1. Use Bex Queries on both Cubes to do the reconciliation.

2. Load data from BPC Cube to a new BW Cube and then write Bex queries on both BW cubes to do the reconciliation.

3. Any other method.

For the First method, if we run Bex Query on the BPC Cube then we would not be able to capture the last yellow request, hence there will always be a mismatch in the reconciliation process.

For the Second method, if we load the BPC data into a new BW cube, then it is unnecessary duplication of BPC data plus additional process chains etc.

Please suggest what is the best practice for such a scenario.

Cheers,

Nitin
