Epicor 9: Error creating jobs from SO or Project

This week, we have been unable to create jobs from Sales Orders or Projects.  We haven't added anything to the system that would impact this so I think it's bad data, but support can't find anything yet.  I'm wondering if anyone else has seen these issues.


Here's what in the log  First this error 50 times or more

(Procedure:  UpdateBase416_A1 db/object/JobMtl.p Line 5946)** Plant Cost record not on file (138)


Then this

(Procedure: 'copyData lib/BOreader/BOReader/p line:474)  BUFFER-FIELD Employee Num was not found in buffer ttQuickEntryList (7351)

(Procedure: 'copyData lib/BOreader/BOReader/p line:474) Unable to evaluate arguments for Temp_Table method (9050)


Job entry throws 7243 and 7241 with a 4GL Stop.   The Queue stops processing MultiCompany entries as well.


Has anyone seen similar behavior.  I'm betting it's bad data since the system has been working up to now, but everyone we talk to is clueless on where to look and of course support can't recreate it.   Any insight would be appreciated.


E10 upgrade is around the corner and it can't come too soon!
