Hi,

OBIEE 12C version - 12.2.1.4.0

I have set of reports which uses measures from two different Fact tables (cross drill) .

Both Fact tables have two dimensions in common (Time--> Date key level & Geo Location).

There is another Dimension exists in both Fact table but at different levels one Fact is at SKU level another Fact is at PRODUCT level.

I have read somewhere that we need to create Level based Measures in order to facilitate the cross drill. in that sense I believe in my case I need to create measures at PRODUCT level for the Fact table which is having data at SKU level.

But the thing what I cannot understand here is, if I create Level based Measures measures at PRODUCT level, those will be static throughout reporting! irrespective of what level of hierarchy you add to the Analysis.

Otherwise what I believe I have to create Level based Measures at each Level of the Dimension? not sure if that make any sense?

Please advise..

1.) "analysis". Not "report". A "report" is a BI Publisher object and that's a different product.

2.)

Where?

It's not "facilitating" it's "making cross-fact queries along non-conformed dimensions possible in the first place."

a) That's why it's called a "level-based measure"

b) it will still react dynamically to everything around it - everything it can be analyzed by that is. Of course not the non-cornformed dimensions.

For all *non*-conformed dimensions, the measure must be at the "Grand Total" level of said non-conformed dimensions. Also the LTS of the fact table must be set to the "Grand Total" of the non-conformed dimensions.

That's not the issue. The issue is rather that you may have an incomplete picture of how modelling with multiple stars and handling of non-conformed dimensions works.
