Hi
Unfortunately not easy to do however definitely possible, the system builds the list of tracking on the fly using the reservation entries and item ledger entries
The process starts with the "Released Prod. Order Lines" page / form in the "Show Tracking ()" section
This then launches the "Order Tracking" form which calls the "OrderTrackingManagement" and builds the records
If you are sure that there will only be one record returned you could duplicate this functionality without opening the form and catch the record to display
Hope this helps
Cheers
Nev
