Multiple prompts for posting periods

Hi,

I am working on a data model where I need to have multiple restricted Key figures based on posting periods

Past Begin/Ending Balances      Current details      Future Begin Ending balances

I have tried various options of multiple analytic views, joins, aggregations, unions with multiple variables.

However, one of the variable disappears at runtime or I get short dumps.

Any idea on how to do that?

Thanks

Patrick
