When you recover a failed WIP, the system log shows delete errors for the failed WIP, as does the end-of-day procedure. Therefore, you should check the system log for such WIPs then check those WIPs for problems.
WIPs fail for a number of reasons, not always when being invoiced. You might induce a delete error when a WIP was being held and no updating function was carried out. Usually if the WIP was recovered, there is no problem.
View the rest of the system log to find entries stating Unknown menu entry - WIP ***** recovered.
Look on the spooler that your end-of-day prints are sent to as you will have a report titled Recover Failed WIP's, listing the WIPs that could have posting or stock errors.
Tip: The most common errors are check postings/stock and Update reversed.
Points to check on the WIPs listed:
Check with the user concerned that at the time of the delete error what he or she was doing in the WIP. He or she may have been invoicing it or carrying out another function such as job card, requisition, and so on. Alternatively, he or she may have been working in the WIP when your system suffered a power cut or other malfunction.
If the user was performing an updating function such as requisition or invoice, it is important to check that the system has updated correctly.
If it involved the de-carding of stock from your stock file, check that the stock levels are correct.
If it involved an invoice or credit note, check that the monies concerned have transferred to the accounts system correctly. If you provide your accounts department with the invoice number and account number, they can do this for you.
If it was a workshop job using a vehicle held in marketing, make sure any dates in Marketing have updated. For example, next MOT and service dates. Also check that any service history entries have also been written to the vehicle record.
If you can still access the WIP, check that its status is as you would expect. For example, an invoiced WIP should appear as costed with all lines on the invoice page at X status.
Check that you can still retrieve the document from the document archive.
After you have checked these points, Point-of-Sale Support staff can advise you how to rectify any discrepancies.
