VMM Tips & Tricks: Add VM to User Role job fails with Error 20413
In New VMM 2012 R2 with CU3 implementation when you try to add VM to existing user role you may see below error
VMM encountered a critical exception and created an exception report at C:\ProgramData\VMMLogs\SCVMM.4e32da1c-645d-42b3-8c79-612d502ca2ff\report.txt.
See the report for more details and search user forums for well-known failure root causes for self-help.
After some investigation I found the error related to VMM DB, After applying the CU3 you need to run same SQL script described in CU1, CU2
Important After you install the update package, you must apply the following SQL script on your Virtual Machine Manager Microsoft SQL Server database for Update Rollup 2 to function correctly.
Please make sure to have a backup from VMM DB before any modification to it. Once script run successfully the VM can be added to user role without any issue
