I need to add some custom fields in sales packing slip. (Account Receivables -> Common -> Sales Orders -> Pick and Pack -> Packing slip) which will open SalesEditLines form. I understand that the data displayed is from SalesParmTable. I need to change the way packing slip journal will be posted. I have already add the custom fields to SalesParmTable and got them displayed in SalesEditLines form. I would like to know in which class the posting process happen so I can modify the posting process? I have already look in SalesFormLetter_PackingSlipJournal but can't seem to find where the tables are inserted.
In AX 2009, I can change something like SalesFormLetter_PackingSlip.initJournal(), but I can't find such function in AX 2012.
Any help is appreciated. Thanks.
You can find the relevant code in SalesPackingSlipJournalCreate & SalesPackingSlipJournalPost classes
The formLetter frame work has been refactored in AX 2012, http://technet.microsoft.com/en-us/library/hh272871.aspx
