Multiple Shipping Routes. The client is using this feature, I have worked in different customizations with this feature. I'm having an issue when I update a sales order, specifically the ship to on the line level and then saving the order (user event script, after submit that is triggered after saving a custom record), the extra shipping groups are not generated. I mean, I'm adding different ship to on specific lines and for every change, a new shipping group should be added. At least that is the behavior when I have created an order via script. The weird thin is that if I update the order manually on the UI, and click calculate, the extra shipping groups are added. So I"m not sure if I'm missing something on the script that should trigger the re-calculation of the shipping groups, my understanding that it is automatically.
