Help Avoiding A Circular Dependency

Hi all,

I am having an issue understanding how to get out of a circular dependency in 4 simple tables. Currently I get the error saying that I cant make a particular relationship active because it would introduce ambuguity. I think this is because if you look at the small model I have, enabling the highlighted relationship would make the whole thing circular.

My issue is essentially that I have an Employee table and I want to be able to associate those employees with various things, specifically Support Tickets, Feedback, Qualifications and so on. So employee needs a relationship to all of those tables. However I also want to be able limit the analysis of these tables by a common date table, so that I can say "# Ticket, Qualifications, Feedback received in the past 90 days" etc.  So I am trying to link the Date table to all these things as well. As soon as I try to do that I get my "ambiguity" problem

 

Given that what I'm doing is fairly straightforrward there must be a simple way that this is avoided or I am misunderstanding how to use relationships properly.

 

Can anyone advise?

 

Thanks in advance

Re: Help Avoiding A Circular Dependency

In case it helps you can see roughly what I'm after. The employee has various aggregate values calculated but at the moment they are not being managed by a common date. So the Reopen Rate column for example is showing the reopen rate for all time, not say the past 30/90/180 days.PowerBI Issue.PNG
