"Warn if jobs are not assigned to all transactions (System-wide)"

Hi Greta 

Currently, while you can assign a job to a transaction with MYOB Business there is no check or preference that can be enabled to warn if a job is not assigned to a transaction.

In saying that, reports like the job exceptions (cash transactions) and Job exceptions (invoice transactions) would be the reports you would be looking at to determine if a job has been added to a transaction or not. Please note that these reports are only available in MYOB Business Pro.
