The Manufacture/Acquire split feature allows the planning systems to automatically allocate a part's demand between manufacturing and purchasing. When inventory part planning is carried out, the percentage of planning requirements allocated to each are specified.
You can indicate whether you wish to use a manufacture/acquire split
in the
Inventory Part window's
Planning tab. In a manufacture/acquire split, you must define the percentage values
to manufacture and purchase, which totals to 100%. You must also indicate the specific supply types to use for the
manufacturing and purchasing proportions. These supply types override the
default supply type for the part.
The manufacturing/acquire split percentages are considered by the Material
Requirements Planning (MRP), Master
Scheduling, Next Level Demand, Inventory Reorder, and Costing features.
Manufacture/Acquire splits are not considered
within the planning logic of Maintenance Repair and Overhaul (MRO), Configure to
Order (CTO) Interim Orders, the Capability Check or Dynamic Order Planning (DOP).
The acquire portion of the split includes all the demands acquired from internal
and external suppliers. In an extreme planning case, there can be
a manufacture/acquire split with the purchasing portion allocated in supplier splits
of 50% internal and 50% external suppliers. Note that packaging rules and lot sizing rules
for both internal planning and supplier minimum can
together cause total requirement quantities to be inflated to exceed actual
demand.
It is also possible to specify how costing will be applied to the manufacture/acquire split proportions when
calculating rolled up material costs. See Costing for further
information.
The manufacture/acquire split can only be defined for parts that can be
manufactured, including the Manufactured, Manufactured Recipe,
and Purchased part types. Purchase Raw and Expense
part types, and parts with planning methods K (Blow Through), T (Master
Scheduling Level 0 Phantom) and O (Master Scheduling Level 0 Part), cannot be manufacture/acquire split parts.
Manufacture/acquire splits can be defined for, but are not considered by the planning
logic of MRO, the Capability Check, CTO or DOP.
