Improved handling of OT transaction changes

As purchase order lines are added or removed from an Advance Ship Notice (ASN) in OT Transaction Entry, the POEBT records are removed and new ones are created automatically. A message is displayed to remind you to manually update the ASN in TWL. Similarly, if changes are made to a container or shipment ID that results in the creation of unnecessary ASNs, the POEBT records are now automatically deleted. TWL ASN information is now displayed in OT Transaction Entry to warn you when additional ASN records are created. The ASNs must be deleted manually in TWL. Note that during TWL receiving, all ASNs and their related POEBT records are closed automatically.
