Error 2868 - Cycle in procedure calls

We are running into the following error message when trying to reconnect
demand to a job in Vantage 5.0.329

Cycle is procedure calls detected in db/trg/labordt/write.p while executing
write trigger for job for job oper (2868).

The workaround (first zero out labor hours, and costs then try again) given
by tech support has not worked - has anyone solved this problem or actually
gotten a work around to work.

Thanks
