The mySAP SCM is one of the mySAP Business Suite solutions to manage Supply Chain Management in an efficient and effective way which brings efficiencies to the supply chain. In this blog, we present the high level role of SAP PPDS (Production Planning and detailed scheduling) within SAP SCM suite.

SAP Production Planning and Detailed Scheduling (SAP PP/DS) is used for short-term planning with exact times in the production plant including in-house production and external procurement. Production planning covers requirements by generating planned orders (to plan in-house production) as well as purchase requisitions or schedule lines (to plan external procurement).

In contrast to medium-term planning in SAP SCM SNP, production planning in the plant is detailed and, in particular, uses exact times. Exact production times for the production of materials are therefore determined.

In material requirements planning within SAP SCM PP/DS, assemblies and components procurement dates are determined considering actual requirements dates of the finished product.

MRP and capacity requirement planning (CRP) can be executed in simultaneously as opposite to planning in SAP ECC. In SAP ECC, two separate steps are needed for MRP and CRP.

When planning is done in SAP PP/DS (i.e. creation of planned order/purchase requisitions or schedule line), it is further sent to ECC6.0 for execution via Core Interface (CIF) .

Whenever some activities are executed in SAP ECC like confirmation of operation, goods issue etc, and then latest status of production is transferred online to APO in order to maintain planning consistent; this cycle of transferring status/data continues till production order gets finished.

Planned independent requirement is starting point for PPDS which can be derived in SAP ECC (Demand Management) and then transferred to APO PP/DS if PIRs are not created in APO DP.

Sales order is also created in SAP ECC which is customer requirement of finished products and also transferred to APO via CIF as customer requirement. Detailed scheduling can then take place using background planning runs, or interactively using the DS planning board.
