Hi!
The SSR service you know from I11 was discontinued. It´s not available anymore in any of the new versions. BUT: It was replaced with something better! These kind of reports can now be done with Query Definitions.
Go to the Aras Update tool and install the "Aras Reporting" app (or go to FTP). There are also manuals that will explain every question you have now. Aras even has a community project to convert your old SSR reports to the new engine.
From my personal POV the previous SSR service never worked great. It used an external engine with limits the amount of possibilities for the users AND Aras. But: SSR set the foundation for the QueryBuilder and TGV concept, so it was an important step in Innovator history. But be happy that we know have better options!
