SAP S/4 HANA新变化-PP生产计划

1、BOM, Routing, Production Version

With SAP S/4HANA, on-premise edition 1511, thefunctional relation between Bill of Material (BOM), Routing and ProductionVersion has changed.

The Customizing for date validity is no longer considered for BOM explosion. Instead, only BOMs with valid production versionare considered during BOM explosion.

Therefore, it is now mandatory for Manufacturing BOMs to maintain the product version for correct BOM explosion.For all BOMs in the system, it is recommended to maintain product versionsusing the report Product Version Migration for BOM (transactioncode CS_BOM_PRODVER_MIGRATION).通过这个tcode生成生产版本

Maintaining product version enables to combinethe BOM and Routing entities which helps in streamlining the release/ revisionprocess in future.

The customizing that determines the items validfor BOM explosion now has the default value ‘2’ (Version with latest valid-fromdate). This customizing is available in DefineModification Parameters under Production-> BasicData -> Bill of Material -> Control Data for Bills of Material.

BOM Explosion for Manufacturing BOM will depend on Production Versions only.

Manufacturing BOM determination can onlyhappen via production version.

选择BOM只能通过生产版本实现，物料主数据MRP4视图，选择BOM这个字段已经没有了。

An interactive migration report hasbeen provided to create new production versions based on existing BOM data.

Run Report CS_BOM_PRODVER_MIGRATION to create Production Versions.

2、PP-MRP - Subcontracting

You only have to create an MRP area for every subcontractor. Of course, it is still possible to create MRP area/supplier-specificmaterial master data if required.

3、Storage Location MRP

The S/4HANA MRP only plans on plant and MRP arealevel. Planning on storage location level is not available in SAP S/4HANA,on-premise edition 1511.

4、Sales and Operation Planning

Sales & Operations Planning (SOP) is aforecasting and planning tool for setting targets for sales and production basedon historical, current, or estimated data. SOP is used for long-term strategicplanning, not short-term tactical planning. Resource requirements can becomputed to determine work center load and utilization. SOP is often performedon aggregated levels such as product groups and work-center hierarchies. Sales& Operations Planning includes standard SOP and flexible planning. Standard SOP comes preconfigured with the system. Flexible planning offers options forcustomized configuration.

Sales & Operations Planning (SOP) willbe replaced by Integrated Business Planning IBP12. Integrated Business Planningsupports all SOP features plus advanced statistical forecasting, multi-levelsupply planning, an optimizer, collaboration tools, an Excel-based UI, andWeb-based UIs.

PP SOP is intended as a bridge or interimsolution, which can be used until IBP is available as part of SAP S/4HANA,on-premise edition 1511 and which allows you a stepwise system conversion fromSAP ERP to SAP S/4HANA, on-premise edition 1511.

5、MRP in HANA

SAP S/4HANA features MRP Live; an MRP runoptimized for SAP HANA. MRP Live reads material receipts and requirements,calculates shortages, and creates planned orders and purchase requisitions allin one database procedure. This minimizes the volume of data that has to becopied from the database server to the application server and back, whichconsiderably improves performance. MRP Live has some additional advantages

including the following, for example:

· The definition of the planning scope is moreflexible. MRP Live allows you to plan a set of materials with all components, materials for which acertain production planner is responsible, or one material across all plants.

· If a material is transferred from one plant toanother then the stock-transfer requirement is not known in the supplying plant until after thematerial has been planned in the receiving plant. MRP Live determines thesequence in which materials have to be planned across several plants.

· MRP Live is a prerequisite for the futureproduction planning and detailed scheduling PP/DS solution in SAP S/4HANA.

Classic MRP is still available as an interimsolution15, which at the moment hasto be used in the following cases:

· Capacity requirements shall be created by MRP (ina future release, MRP Live will also be able to create capacity requirements).

· For creating MRP lists.

MRP live differs from classic MRP in thefollowing aspects:

· MRP live does not write MRP lists.

· Multi-level, make-to-order planning (transactionMD50) is not optimized for HANA.

· Individual project planning (transaction MD51) isnot optimized for HANA.

· The creation indicator for purchase requisitionsis not available in MRP Live. MRP Live always creates

purchase requisitions if the material is procuredexternally.

· The creation indicator for delivery schedulelines is not available in MRP Live. MRP Live always creates

delivery schedule lines if a valid deliveryschedule exists.

跨工厂跑MRP最大的好处是对集团内多工厂相互供料，存在STO转储的需求，则可以通过跨工厂MRP统一考虑。

6、Forecast Based Planning

In forecast based planning (MRP type VV)the MRP creates planned orders or purchase requisitions if total forecast demand up to a certain pointof time exceeds the total firmed receipt quantity up to the same point of time. The total firmedreceipt quantity includes inventory, production orders, purchase orders, firmed planned orders, andfirmed purchase requisitions. Forecast based planning is a simple planning procedure, which does notrequire managing planned independent requirements.

For Forecast based planning the followingthings need to be considered:

 MRP live does not perform forecast basedplanning in HANA but sends the affected materials into the classic ABAP planning procedure.This results in a performance loss.

 Forecast demand and planned independentrequirements are semantically very similar. SAP S/4HANA tries to avoid redundantfunctionality.

The Fiori-UI for planned independentrequirements does not differentiate between forecast and planned independent requirements. A statisticalforecast is just one of several possible data sources and the result is always plannedindependent requirements. SAP will not build separate Fiori-UIs for

forecast demand.

In the long run forecast based planningshould be replaced by MRP type planning. Proceed as follows:

 Step 1: Convert forecast requirementsinto planned independent requirements (PIR)

 Step 2: Change MRP type VV to one of theMRP types PD, P1, P2, P3, or P4

7、Planning Horizon

The SAP ERP MRP covered material demandinside the planning horizon only if processing key "NETPL" was used. It covered all material demand if processing key "NETCH" was used. Planning inside the planning horizon was aperformance measure intended to improve MRP runtime. With planning inside the planning horizon, MRPhad to create fewer planned orders and was therefore running faster. This was achieved at theexpense of a more complicated planning procedure.

Planning horizons for materials ondifferent BOM levels had to be aligned. Periodically, net change planning with processing key"NETCH" had to be performed in order to create planned orders for material demand in the more distant future.

The S/4 MRP always covers all materialdemand. Planning inside the planning horizon is no longer available. Thanks to performanceimprovements of MRP in HANA, the additional performance improvements of net change planning are negligible anddo not justify the additional effort.
