Running into a modelling issue * Need your help

Hello guys,

I am running into a data model issue, where it seems that I can't find any plausible solution for this.

Context:

Company Segment: Debt Collection Company

Data Model:

3 fact tables:

f1) reports the current amount for each case the debtor has open in our company

f2) reports the receivables from our debtors

f3) reports the agreements reached for each debtor and case.

Other Dimension Tables:

d1) case level

d2) debtor level

d3) date

and so on

Situation:

We are now conducting three distinct campaigns (email, SMS, and so on) for the cases that we have in our organization. The issue is that the incidents may appear in multiple types of campaigns.

Question:

I want to add a campaign name-based filter to a PBI table, to get the payments, agreements reached for the cases included in each campaign.. How is that even doable if my campaing table has no distinct values? I've tried with a bridge table, but doesn't seem to help either..
