OK, I figured out what the difference between get_related_list and get_dependents_list is. I've created a UI10 field in PurchaseOrders and setup a get_dependents_list entry. But I'd like to add BOTH related types to salesorders. So a related list that shows but the related through a UI10 field, and the related through the vtiger_crmentityrel table. Is that even possible?
Also, the problem I have when setting up a relation through get_related_list is creating a new record in this way does not setup a row in vtiger_crmentityrel.
