At various times, it is necessary to test connectivity to a SOAP web service from your SBM server. Internally, SBM makes web service calls to itself. SBM Orchestrations often will call the Application Engine web services, but will also make web service calls to third party tools.
This may be an issue with the way users were imported / created in SBM . Perhaps, this is caused by an upgrade from an old version of TeamTrack. Check the TS_TIMEPREFERENCES column in the TS_USERS table in the Application Engine database for the user. The only valid values for TS_TIMEPREFERENCES are 0 or 1. If you have any other value in TS_TIMEPREFERENCES, replace it with a 0 or 1.
