Manufacturing Process in SAP Production Planning

PP-Discrete:  Required where there will be discrete orders passing through a work center, here the capacity planning plays major role. i.e. if you have a lath machine, many orders are going through this lathe m/c and schedule plays very important role w.r.t lath as well as the product as the product has to go through many work center. Every time the product many not be same can be different, but same work center can be used for many products.

PP-PI: Mainly concerned with quality parameters and Process management i.e control recipe is configured in this module. But the difference is the o/p is almost same, you will not change the product, but every step is very important to achieve the product quality. And it is entered by operator and approved by shift supervisor through control recipe function.

PP-REM: Mainly to reduce the data input by person working in SAP and in this case we are bother by the period end costing and not the each order level costing as the process is repetitive and one order is sufficient for the whole life.

 

Characteristics of discrete, process and repetitive manufacturing types:

Characteristics of production type	Discrete Manufacturing (SFC)	Process Manufacturing (PP-PI)	Repetitive Manufacturing (REM)
Product stability / complexity	Complex production process with intermediate storages	Complex production process and generally without bulk intermediate storage (mostly continuous-flow and liquid-based production)	High-volume or mass production, highly stable and without any production complexities
Production flow	Order-based and with intermediate storage	Order-based and mostly used in producing materials that flow, such as liquids, (or that can't disassemble)	Lean (simple) manufacturing
Change-over from one product to another	Frequent	Frequent	Infrequent
Make-to-stock and make-to-order production method	Supported	Supported	Supported
Batch management	Yes	Yes (extensive utilization)	Yes
Active ingredient management	Not available	Available	Not available
Material quantity calculation	Not possible	Possible	Not possible
Completion confirmation (backflush)	For individual operations or orders	For individual operations or orders	Period-based confirmation with backflush
Order-related production	Yes (production order)	Yes (process order)	No (planned orders)
Production-based	Lot size-based production	Lot sized-based production	Period- and quantity-based production
Cost object controlling	Order-based costing	Order-based costing	Period-based costing (using product cost collector)
Process management	Yes (process integration)	Yes (process management)	No (operational method sheet)
