S/4HANA with Embedded PP/DS Functionality

SAP APO (Advanced Planning and Optimization) application has been transformed into SAP IBP (Integrated Business Planning) and S/4HANA (Business suite 4).

The below picture at a glance overall application merge with successor modules exchange IBP and S/4HANA. In this blog focused on Production Planning and Detailed Scheduling (PP/DS) functionality with S/4HANA.

Production Planning and Detailed Scheduling (PP/DS)

SAP S/4HANA for Manufacturing planning and scheduling Comprehensive Plan to Produce in ONE System is a great advantage to plan production process very detailed level.

PP/DS planning and scheduling features available in SAP S/4HANA

  • Constraint-based capacity planning, scheduling & optimization
  • Heuristic framework
  • Industry-specific features (RPM, MMP & CBP).
  • Simulation versions and transactional simulation.
  • Supports various manufacturing models:
    • Make to Stock
    • Make to Order
    • Engineer to Order

One MRP

  • One MRP planning runs for classical MRP planning and advanced PPDS heuristics.
  • One low-level code calculation

Simplicity and Seamless Integration

  • One coherent application, consistent look at feel, intuitive navigation PP/DS is an integral part of S4/HANA (not an add-on, not a side-by-side installation).
  • Simplified master data and integration model maintenance.

Utilize HANA (HANA only)

  • Fast MRP [ One MRP for infinite planning ]
  • liveCacheis integral part of HANA, just one database to manage

PPDS mainly covers the following requirements.

  • To create procurement proposals for in-house production or external procurement to cover product requirements
  • To optimize and plan the resource schedule and the order dates/times in detail

You can take the resource and component availability into account here. Above all, PP/DS is used to plan critical products, such as products with long replenishment lead times or products that are produced on bottleneck resources. You can use PP/DS to create executable production plans and:

  • Reduce lead times
  • Increase on-time delivery performance
  • Increase the throughput of products and reduce the stock costs, through better coordination of resources, production, and procurement

Basic Configuration Settings

Advanced planning function activation

In order to switch Advanced Planning function, you have to enter Customizing (transaction SPRO) Advanced Planning  -> Basic Settings -> Activate Advanced Planning and Scheduling.

Once this advanced planning function activated the following SAP Fiori apps can be accessed.

  • Monitor Capacity Utilization
  • Production Scheduling Board
  • MRP app Create Optimal Orders for Shipment
The apps activated by the Advanced Planning and Scheduling switch are not part of the standard SAP S/4HANA Enterprise license. A dedicated license for Advanced Planning and Scheduling is required if this switch is set to Active.

Data transfer settings

Define the transaction data that can be transferred from SAP ERP to SAP APO and vice versa. In other words, you can select for transfer those order types that should be advanced planning-relevant this includes:

Global Settings – Global Parameters

The system will only use these default values if you have not specified any values in the master data or the applications. Check the parameters delivered in the standard system or maintain your own parameters and profiles and assign them.

Set up the Model and Planning Version (Transaction /SAPAPO/MVM)

Set up the Model ‘000’ and Version ‘000’ manually and check whether they exist. The PP/DS Horizon can only be maintained at the level of planning versions in SAP S/4HANA and it is not possible at Product-Location combination.

Core Interface settings (CIF)

Access CIF integration settings and maintain as below to communicate data transfer within the same instance.

Integration via Core Interface (CIF) -> Integration -> Basis Settings for Creating the System Landscape

Name Logical System

Assign a Logical System to a Client

Set Up RFC Destination (self RFC as classic tRFC (transaction SM59)

Maintain Business System Group (For the APO part)

Assign Logical System and Queue Type

Maintain Operating Mode (ECC Part) (transaction CFC1)

Specify SAP APO Release (Transaction NDV2)

Master Data Creation and Transfer

Setup and activation of Locations

Location Type, Business Partner (1021), replaces Customer (1010) and Vendor (1011)Execute reports mentioned below create and update locations

  • Create – /SAPAPO/CREATE_LOCATION for creating Business Partner location, Plant, MRP Area and Shipping Point.
  • Update – /SAPAPO/UPD_LOC_SP_PL for updating Plant, MRP Area and Shipping Point

Setup and activation of Materials

SCM Product Master is integrated into the SAP S/4HANA Product Master with CDS Redirects on material master.

  • Local material creation in PP/DS is not supported.
  • Activate PP/DS Materials by selecting the “Advanced Planning” checkbox in the “Advanced Planning” tab of the material master.

Material master ->Advanced Planning -> Advanced Planning (Transaction MM03)

After activation of advanced planning function material PPDS product master updated automatically.

Product master (Transaction /SAPAPO/MAT1)

Setup and activation of Resources

  • Local resource creation in PP/DS is not supported.
  • Enable Target-System independent Settings in CIF (Transaction CFC9) to enable “APO Resources” in Work Center Capacity: header tab. This is required to send to PP/DS different resource types and resource categories. This would be required to transfer handling unit, calendar resources etc.
  • Activate PP/DS work centers by selecting the “Advanced planning” checkbox.

Work center -> Basic data -> Advanced Planning (Transaction CR03)

After activation of advanced planning fucntion in work center resource information updated in PPDS function automatically.

Resource (Transaction /SAPAPO/RES01)

Setup and activation of Source of Supply

In-house production:

  • BOM for phantom assemblies mandatorily need production versions and need to be transferred to PP/DS using CURTOADV_CREATE.

The prerequisite to transfer PDS is to create BOM, Work center, Routing and production version.

Production data structure (Transaction /SAPAPO/CURTO_SIMU)

Here is the simple production structure.

Finished material – F-100-102

Raw material – R-100-102

External Procurement: (not focused on this blog about external procurement).

  • Create the integration model for scheduling agreements, contracts, and purchasing info records which need to be integrated to PP/DS should be used using integration model maintenance and activate it

Process Execution

The first step starts with the forecast update for finished material F-100-102.

Creation of PIR (Planned independent requirements) – (Transaction MD61)

Stock requirement list (Transaction MD04)

Product view (/SAPAPO/RRP3)

Forecast automatically transfers to PPDS function and able to display forecast in production view.

Production planning run (/SAPAPO/CDPSB0)

You use the production planning run to execute planning online or in the background for selected objects. In this case, online planning is only suitable for small data quantities (for example, for test purposes), while you implement background planning for mass planning. Depending on the planning problem being solved, you use heuristics, PP/DS optimization, or Detailed Scheduling (DS) functions in the production planning run. In the production planning run, you can execute various planning tasks in several consecutive processing steps using different heuristics or functions. For example, you could first execute procurement planning for products with uncovered product requirements using a product heuristic, and then execute sequence optimization on the relevant bottleneck resources.

After planning run completed planned orders created (stock requirement list).

Heuristic run executed at multilevel and purchase requisitions created for raw material R-100-102.

The same requirements updated in product view automatically by the heuristic run.

Production detailed scheduling board

You schedule interactively with the help of the detailed scheduling planning board to solve scheduling problems at resources; for example, problems with dates and sequencing problems.The following standard heuristics are supported while working with Production Scheduling Board

  • SAP001 – Schedule Sequence
  • SAP002 – Remove Backlog
  • SAP003 – Schedule Sequence Manually (Fiori UI pop-up supported)
  • SAP004 – Minimize Runtime
  • SAP005 – Schedule Operations
  • SAP_DS_01 – Stable Forward Scheduling
  • SAP_DS_02 – Enhanced Backward Scheduling
  • SAP_DS_03 – Change Fixing/Planning Intervals
  • SAP_DS_04 – Activate Seq.-Dependent Setup Activities
