I have published some reports I've built using SQL Server Reporting Services, but when I try to retrieve data, I get the error message on the title.
Inside SQL Data Tools, I can connect succesfully and can see data using the "Preview" tab.
Testing the Data Source (PI_AF) is also succesfull.
PI SQL commander connects fine to AF Server.
I have switched both PI OLEDB Enterprise Agent and SQL Server Reporting Services to run with the same admin account (the same one I am accessing the browser).
What other permission am I supposed to configure?
