is there any screen or any field to show when the packing slip is cancelled.
There is a form called CustPackingSlipJournalHistory. If you open it from the AOT, it shows all Packing slips. You may be able to identify Packing slip Corrections or Cancellations from normal Packing Slips by the Voucher number. There is a different number sequence for each, so its possible to define a different format for the voucher of a cancellation.
(I can’t find a way to open this form, and show all Packing slips, from within any menu).
If you Personalise this form, you can Add a field from ‘Customer Packing slip versions’ called ‘Change date’. This appears to show the date that the cancellation was posted.
