How to design Compounding char in Infocube?

I have two infoobjeccts, Cost Center and General Ledger. I assigned Cost Center as the compounding of General Ledger. In this situation, how can I design the infocube? If I assigned these two infoobjeccts as different dimensions, "No Applicable Data Found." problem happened in report. If I assigned them at same dimension, no this kind of problem. Although they are compounding, they are different issues. Based on business logic, I think they should be assigned at different dimension.

What's solution when you met this problem? Give me some advice please.
