When assigning web-based (i.e. Self-Service-style) responsibilities to your applications user account, and then trying to navigate immediately to that responsibility, this error often appears.
“Tax Managers is not a valid responsibility for the current user. Please contact your System Administrator”
To resolve this issue, you must clear the applications cache, or bounce the Apache server.
To clear the cache:
Resp: Functional Administrator
Nav: Core Services > Caching Framework > Global Configuration > Clear All Cache
