report type "common field error"

I have a primary object called "Personas". And I have couple of other objects which has either Master-detail or lookup relation to "Personas". Since we are allowed to go maximum upto 3 objects in report type, I had to create another report type...still all has lookup relationship to "Personas". But when I add the second block, I gets "Common Field Required" error.  Please help

Hi Vinu,

By the error I see there should be some common field between two reports.

Can you check (https://help.salesforce.com/s/articleView?id=sf.reports_joined_format_concepts.htm&type=5) this article for the same.

Let me know if you face any issues.

If this solution helps, Please mark it as best answer.

Thanks,

Yes Praveen. I have all object lookup to "Personas". My first Object in the first Report type is "Personas". Then objects Permission, Epic, User Story.

Second Report type start from Object, Field Access.

All these object has a common lookup to "Personas". 

When I add the second block, i get the common field error
