hey Steve,
I am not a programmer and I dont work for method but I have been thinking about this. My concern is if you have a customer that has 4 contacts and each contact has a unique number, when creating a WO how is method going to choose that unique number if there are 4 contacts? See where I am getting at?
When using a drop down field have the logic choose your contact number as well thats if its in the same table. The customer would show 4 times but you would see a contact name and number next to the choice. I think its possible.
One of the Method team should be with you shortly.
