DataAreaId and ProjDataAreaId in Query

Hello everyone,

I have been working on cubes customization and I have the next scenario:

TSTimesheetLine table has two fields that can determine dataarea for different purposes: DataAreaId - company dataarea value, ProjectDataAreaId - dataarea of the project.

I need to create a relation in query to ProjTable, but using not DataAreaId, but ProjectDataAreaId. Making this, I always get three fields in relation part of query (looking at from SQL Manager), where I have ProjId, DataAreaId and ProjectDataAreaId. But I need only ProjId and ProjectDataAreaId.

Is there any solution for this?

Thanks a lot for any ideas.

Update: I am working with AX 2012 trying to perform this.
