Hi @mbasha_123 ,

According to your screenshot, I think your issue should be caused by relationship.

Relationship 1 :

'Customer_Detail_Customer_Details'[Column] → ‘Customer_Details_Platform'[Column] → ‘CustomerMatser’[Column]

→ ‘Product_or_Module’[Column]

Relationship 2 :

'Customer_Detail_Customer_Details'[Column] → ‘Product_or_Module’[Column]

We can see that 'Customer_Detail_Customer_Details' table can filter ‘Product_or_Module’ in two relationship directions. So Power BI will throw this error.

I can reproduce this error on myside.

I think you may get error when you use unsummarize function in table4 column. You relationship doesn't support the visual to expand with data in full four tables.

It's normal that it's throwing an error.

May I suggest you either not use the many-to-many? Or that you build a 'snowflake' like model, with relationships streaming from a center table?
