Error in linking Sale Order to Old Job Num

Hi All,
I am running vantage ver 5. Trying to link new Sale order with old Job
number. I am getting error message "Cycle in Procedure calls detected in
db/trg/labordtl/write.p while executing WRITE trigger for JobOper. (2868)".
What is the reason ?

With Regards
