    Hi Anonymous 

     

    Thanks for using Microsoft Fabric Community

    Here's how to join two Excel files in Fabric Dataflow with an inner join based on multiple columns, considering a value in a separate column. Fabric Dataflow offers a powerful tool called Filter that allows you to achieve this conditional join.

    I hope this information helps. Please do let us know if you have any further queries.

     

    Thank you.

Could you create one (or more) custom column (populated with values only as per your conditions) and then use the custom column in the join instead of the original column(s)? 

 

Or maybe you can edit the power query code in Advanced Editor to facilitate your needs.

 

(Otherwise, I would consider posting this in the Power BI desktop forum because this is essentially a universal Power Query question, not specific to dataflows gen2, and there may be some Power Query experts in that forum)
