Hi All,
Hope you all are doing good.
I have requirement where I had to add a enum field on SalesEditLines form like below during the time of Sales Order Packing Slip Posting, so I added that field in SalesParmUpdate Table :

Now I wanted to populate this custom enum field to Yes whenever Packing Slip Posting form is opened only if a related intercompany Purchase Order exists for that particular Sales order.
Can someone please explain in detail how can i achieve this? Where exactly to code?
Also how can I make this custom enum field visible in Sales Edit Lines form only during Packing Slip posting process? As this form is being using in other process, like sales order confirmation,etc.
Please help!!!
Thanks in Advance.
