Andrew,
Yes, integrity check finds those problems.
Bruce,
That's what we were doing, but now that the jobs are corrected, there are still instances of those incorrect "managers"
Tech Support,
Thanks, that was what we needed - the name of the file to use in Gridview. We did find them in the Assign Managers/Dates/Prices function. Once assigned to the job, the manager carried to all phases, so we had to clear them out here as well.
