Following error made me worried when I was not able to run (existing or customized) SSRS reports from AX. Reports were working fine few days back and there wasn’t a single change done neither at report server nor with AOS service accounts.
After digging into issue, came across the issue was services and services groups in AOT. My AOS was connected with TFS and when I got latest from TFS it affects SRSFramework and SSASFramework services and there was some sort of reference lost in service groups.
