Attribute Cross Join

Attribute Cross Join

Attribute Cross Join

(OP)
I have 3 tables: A, B & C.

A joins to B & B joins to C.  When I pull data from A & B, or B & C, everything works fine, but the moment I pull from all 3 tables, I get a cross join on one table.  

Any ideas why the Join suddenly fails?

All the objects are Attributes.  The joins are heterogeneous & work fine when only used with one other attribute.  It seems to not recognise a Join that previously worked.  Anyone out there come across this before?

RE: Attribute Cross Join

(OP)
A fix has been recommended by MicroStrategy (which works perfectly):  

The problem is with the Relationship between the tables.  When using a Star Schema, the joins need to be Many To Many.  Using a 1:Many relationship creates Cross Joins when used in a Star Schema set up.
