According to the Oracle SCM Business Process Certified Foundations Associate Rel 2 document1, WIP,
Contract Manufacturing, and Supply type are three item attributes that belong to the Manufacturing
Attribute group. The Manufacturing Attribute group contains attributes that define how an item is
manufactured or procured. WIP is an attribute that indicates whether an item is enabled for work in
process (WIP) transactions, such as creating and releasing work orders, reporting material and
resource usage, etc. Contract Manufacturing is an attribute that indicates whether an item is
manufactured by a contract manufacturer (CM) or by an original equipment manufacturer (OEM).
Supply type is an attribute that determines how material is issued to a work order, such as push, pull,
bulk, supplier, etc.
