I have a custom field in both PurchParmLine and VendPackingSlipTrans tables. I want to set the value user enter while creating product receipt from PurchParmLine to VendPackingSlipTrans.
I have checked initJournalLine and updateJournalLine methods in PurchPackingSlipJournalCreate class which have the initialization logic for VendPackingSlipTrans table but I couldn't find a way to apply me logic in between those methods using chain of command as the table buffer for VendPackingSlipTrans is private and not accessible in extension class.
Is there any way to use these methods or any other suitable method for initializing VendPackingSlipTrans table using extension?
