Multi Fact RPD with Compatibility Error

Question

All,
I was wondering if you can help with this issue.  Here is a picture of my RPD model in Oracle OBIEE 11g BI Administrator:

It is in the format D1 <-- F1 --> D2 <-- F2 --> D3.
In the picture you can also see the Logical Level settings for one of the Logical Table Sources and one of the Measure columns.
When I try to create a report in OBIEE, OBIEE throws a SQL error.  It doesn't understand how to relate D1 to D3.  My requirement is to build an RPD that supports a report like this:
D1 Column | F1 Measure Aggregated | D2 Column | F2 Measure Aggregated | D3 Column
minus any cartesians.  I haven't even gotten to the cartesian error (which would be a good sign I am on the right track), i just get the error:
None of the fact tables are compatible with the query request AWARD_SUMMARY_DIM.AWARD_NUMBER
We have also tried smashing F1 and F2 together into a single Fact within Business Model and Mapping with the same results.
Thanks,
S.

Answer 1

Srini,
First, thanks for your support.
Second, I went into F1, then sources, then the Logical Table Source properties General tab and added D2, then F2.  After updating the Presentation layer and restarting OBIEE, my report still returns the same error.
I tried to force the join on F2 next.  Same as above, but in reverse.  I added D2, then F1 as sources for F2.  Same error remains:
None of the fact tables are compatible with the query request AWARD_SUMMARY_DIM.AWARD_NUMBER (D1).
