Unable to delete User object in FIM Portal - Cannot find the object "#calculateRequestSetTransitionsAssembleStatementsPartition"

Question

Hi,
***Problem
I encounter a problem with FIM (version 4.1.3441.0 and 4.1.3496.0) when I try to delete a User object (and only a User object) whatever if it is
manually/Expiration Workflow/Powershell.
Deleting a User object used to be perfectly functional and, without any product version modification, stopped working. I haven't neither deleted/modified or add a
"Grant" MPR or any of the corresponding Sets since last time I saw it working.
Displayed error is "Request could not be dispatched" in FIM Portal and is referencing a stored procedure in Event Viewer.
***Error details
When I try to delete a User object, here is the output :
Portal
"Processing error" on submit
with the following details 
Request status is stuck at "Validating" until next restart of FIM Service (after what it becomes “Canceled”)
Request’s “Applied Policy” tab does not contain any MPR where, at least, a “Grant” MPR is expected
As SQL Timeout is relatively high and error happens quickly, I don’t think there is a Timeout problem under that.
Logs
« Application »
The Portal cannot connect to the middle tier using the web service interface.  This failure prevents all portal scenarios from functioning correctly.
The cause may be due to a missing or invalid server url, a downed server, or an invalid server firewall configuration.
Ensure the portal configuration is present and points to the resource management service.

For information, a maintenance plan rebuild/reorganize indexes daily and this problem has occurred on servers with different performances.
Is any of you has already encounter this problem ?
Any help would be greatly appreciated,
Thanks in advance for your help,
Matthew

Answer 1

While there are several SQL Agent jobs (FIM Temporal Events, Maintain Sets, and Maintain Groups among others)created by the FIM install only one of those is enabled and scheduled and it calls all of the same stored procedures that the other
jobs do. Step 2 is Maintain sets and Step 3 is maintain groups. So the Maintain sets and groups jobs never need to get enabled and scheduled, but if you want them to be maintained more frequently then you can.
