I am new to OBIEE 10G.
I have a DimA (dimension), FactA (fact). I mapped foreign key relationship between DimA and FactA on DimA.A = FactA.A in BMM, the relationship is inner and greyed out, so I can't change it to outer join.
So in the answers report, it only shows data of the inner join of the two tables. What I want is to show all items in DimA and related items of FactA or 0 for those not related.
I have posted a similar question here before https://forums.oracle.com/thread/2596618 But I still can't modify the relationship (still greyed out) even if I opened a offline repository.
And what I am thinking is is there an option in answers to dynamically control the join (inner or outer). For example, sometimes I want to show only matched DimA and FactA , sometimes all DimA and related FactA or 0, so that I don't have to modify the BMM in repository every time if the requirement changes.
What's the best practice for this case?
Thanks.
--update
I found in physical diagram, I can't change the type of relationship (complex join or foreign key). But in logical diagram I can change for both.
