SQL Server version is 11.0.5569.0.
The user/login for the process on a server is as follows:
This is not an orphaned user (as suggested below) because I checked that before entering this post.

sp_whoisactive. The explain plan indicates that this is working with a couple of temp tables that it obviously created in a prior step.

Any other suggestions?
