Item Dependencies refer to processes that must first be completed before the item can be processed. It may also depend on another item being in stock.
Creating item dependencies assists the smooth flow of processes because potential bottlenecks can be identified ahead of time.
Dependencies from both Item Costings and linked Estimate Costings are shown in the Dependencies (tab) in the Item Edit Form.
Navigation: Main Menu > Setup > Settings > Users (tab) > Click any user
Items & Inventory > Dependencies Actions - Access Allowed: Checkbox that if checked will give the user access.
Dependencies are set up when an item is created or edited.
