Some work orders are instructed as have a date instructed field populated on Work Order form ( mai3800). However the status is still Draft and the Instruct button is now saying Complete. The status should say Instructed.
Check if interfaces are on and if the work order line has passed the information to the contractor. The interface tables will show if this has occurred. This had happened for this issue, so given the information had been sent across the interface the issue was to get the Client system to reflect the correct status. From the work order line screen see if the work order line status can be changed to INSTRUCTED. This was allowed on this occasion. This resolved the issue.
The issue was caused by loss of comunication to a mail server so caused an incomplete transaction.
If this does not resolve the issue please contact the support team.
