      Here's a different view of your data model. That Documentation table looks weird. What's the story behind it?

       

       

      What is the first buy column intended to achieve? There is also a data quality issue for Documentation Nr. 4996 - conflicting customer IDs.

       

       

       

      Bidirectional = bad.  This here is Power BI, not Qlik.  Power BI wants Star schemas.
