TDS Endpoint multi value parameter PBRS

Hii lherbert501 

The TDS endpoint expects strongly typed scalar parameters, so IN (@Team) or JSON parsing won’t work, which is why it throws “@Team was not supplied.”

Correct approach: Let Report Builder handle the multi-value expansion automatically by using:

t.name IN (@Team)

Then ensure the parameter is configured as Multi-value and the dataset query type is Text (not stored procedure). Report Builder will internally expand it to multiple scalar parameters (@Team1, @Team2…).

If this still fails, the limitation is from the Dataverse TDS endpoint, which does not fully support multi-value parameterization  in that case, you must switch to FetchXML or Power BI semantic model instead.
