Table Relationship Issues

Hello,

 

I have a sales by serial number and claims by serial number table and the only common field is the serial number.  Both tables can have the serial number listed more than once for various reasons, so I created a unique key table with the serial numbers from the sales table only listed once and created a relationship to both tables.  When I try to create visuals with information from both tables, I recieve an error that it can't display the visual because it can't determine the relationship between two or more fields. 

 

I am looking for suggestions on how I can get claim data visuals for serial numbers sold.  I have tried to use LOOKUPVALUE and RELATED or RELATEDTABLE without success, but maybe I am doing something incorrectly.

 

Any suggestions or guidance will be appreciated.

 

Thanks in advance

    Hi szub,

     

    do you have a screen shot of your model? Or could you share the report?(upload to onedrive/dropbox/other and share the link).

     

    Cheers,
    Sturla

        Provide sample data for transaction and claims tables.

    Hi szub 

    Modified "SERIAL_NBR" column of your "TransactionData" table as below

    Create relationships

    srial 1 has 1 row record in "Claim" table, serial 1 has 2 rows in "Transaction" table, so wen adding columns from two tables in to a visual, it shows all data from two tables like crossing join.

    Best Regards

      Hi v-juanli-msft ,

       

      Thank you for your response.  I realized that I did not have a serial number listed more than once in my sample Sales Transaction data once I had left for the day and have now corrected.  Thank you for realizing that.   

       

      All the training and dicussions I have had with others have advised to stay away using many to many relationships, which is why I did not use it.  Are there any negatives that you have experienced with using Many to Many?

       

      Thank you

        could  you also make a mockup in excel of how you want your table/output to look like?
