I am trying to join two tables T1 and T2.
T1 has a calculated column which is concatentation of fields Type and Age.
T2 comes from excel and had the fields Type and Age concatentation performed in excel prior to loading.
When I try to join, get error where it believes relationship is many to many.
Can pull individual fields into Power BI and join back to T1 w/o issues.
Also spot checked the data and do not see any issues with T2 i.e. concatenated field is unique.
Any assistance would be appreciated.

Blanks and nulls can trip you up. Every single value/row in the table on the 1 side of the 1:Many must be unique. So if you can have blank values in this column and there are more than 1 row with a blank column, you will fail this referential integrity test.
