I created a SS following the instructions in the article. The issue is that the list is returning ALL Contacts in my NS Environment and NOT those filtered to the customer on the Sales Order.
I have done this before where the filter would usually be the The Company internal ID field and not show in filter. I have tried each of the following fields. Company, Primary Company, Customer and Primary Customer. I also tried each of the following fields with the Company Internal ID etc.. and no success.
If the customer is ABC Company I only want to see the Contacts for ABC company in my Sub list
