@Zerobertson First off. Did you get your field to show? I would look in Customer Shipment Entry in Line then the list tab. All of my custom fields show there. If not there is a log of schema errors.
Assuming the field appears, I would put this post processing on the method GetOrderRelInfo.
Three set variables to ShipDtl.OrderNum, OrderLine and OrderRelNum
Then query
Columns. I am using ShortChar01 since I did not add a field for this example
Set relations and bind your field.
