We are working to retire old EAs from Production, but most of the Date EAs have Object Relationships which would need to be cleared before the EA can be deleted.
From Aprimo Product (thanks Jeff!), we learned... The relationship is automatically generated on date EAs, and since it's a 'Standard' relationship, it can't be deleted -- even if it's never been used in a report. The model was intentionally designed this way.
This request is to remove that restriction. We would assume that we'd still have to first delete any reports or report fields that leverage the relationship, but this should allow us to remove the unused relationship and delete the obsolete EA.
