Bridging Table not working as expected

I have two tables that I need to show data from. They both have a 'National Code' that is not unique in either table. I am trying to use a bridging table consisting of one column with a comprehensive list of unique 'National Code's. The visual (a Table) that contains info from both tables errors. Can anyone tell me what I am missing here? Here's screenshots of a moc example:

 

 

 

  • Hi Anonymous ,

     

    It’s prompted that can’t display the data coz power bi can’t determine the relationship between these two tables.

    Why don’t you try to set the relationship bwteen CourseMasterData with LearningBankData1 directly?

      I am not using any measure, just the 'CMD_National Title' from the 'CourseMasterData' and the 'LB_Info'from the 'LearningBankData1' as per the screen shot. The error is shown in the screen shot also.

      No that did not work. Here's a link to the file.

      Thanks Frank,

      Yes this works thanks. I was using an older version of PBI which did not have the many to many cardinality. I have now got the new version and the many to many works just fine. Thanks
