Function documentationPP/DS Deployment Heuristic Locate this document in the navigation structure

 

The PP/DS Deployment heuristic allows you to select the process to be executed for stock transfers during PP/DS deployment. On deployment, the system reads the orders for the selection from LiveCache and the master data.

After production is complete, deployment determines which demands can be fulfilled by the existing supply. If there are insufficient quantities available to fulfill the demand or if the quantities available exceed the demand, PP/DS deployment makes adjustments to the plan created by the PP/DS planning run.

The deployment heuristic invokes the PP/DS deployment algorithm, which generates deployment stock transfers based on the PP/DS stock transfers that were created during the PP/DS planning run. The Transport Load Builder (TLB) then uses these deployment stock transfers to create transport loads, thus generating TLB shipments. The PP/DS deployment also enables characteristic-based deployment.

Features

Distribution Plans

You can use this heuristic to create a distribution plan for one product at one location. Real-time deployment does not take place. If the available quantities are insufficient to fulfill the demand, the system uses fair-share rules to determine the distribution plan. Only pull deployment is applicable in PP/DS.

Quantity Confirmation within Order Segments

PP/DS deployment can now confirm quantities in order segments, such that the same document flow as for Make-to-stock (MTS) orders is followed. The planning runs separately for each order segment.

Processing of Stock Transfers

PP/DS deployment has capabilities similar to Supply Network Planning (SNP) deployment. It confirms quantities that can be transferred and changes the planned stock transfers accordingly. You can opt for either of the following procedures on the planned PP/DS stock transfers:

  • Delete: Enables the creation of deployment stock transfers and deletes all PP/DS stock transfers that fall within the planning period, regardless of whether or not they could be confirmed during the deployment run.

  • Change: Enables the creation of deployment stock transfers and reduces the PP/DS stock transfers accordingly.

  • No Processing: Ensures that the system does not create any deployment stock transfers and does not reduce the existing PP/DS stock transfers. This option is for simulation purposes only. You can view the results in the log.

ATD quantity is calculated based on the ATI and ATR categories.

Deployment Horizon

The deployment horizon setting allows you to define the number of days the system must consider during the deployment calculation. Unless you process the deployment run in batch mode, using the background job scheduling function, the current date is taken as the start date for the run. This horizon is shorter than the SNP horizon since SNP is the input for deployment planning.

The existing SNP deployment function has been incorporated into a standard PP/DS heuristic, SAP_PP_024. This approach provides the following capabilities for PP/DS deployment:

  • The heuristic can be called from the PP/DS Product View or started from the background.

  • The heuristic fits into the Process Chain tool just like any other standard heuristic.

PP/DS deployment is different from SNP deployment in the following areas:

  • Only pull distribution is allowed.

  • Fair-share situations can only be resolved with Fair-Share A and Fair-Share X options.

  • The planning run uses only the new standard Planning Book 9APPDS_DEP, which defines a long-term daily bucket structure and macros relevant for this scenario only.

  • Categories of confirmed stock transfers can be seen at PP/DS Global Settings

Master Data Changes

The following new fields have been added to the PP/DS tab screen of the Product Master:

  • Depl. Char. Prof.

  • Fair-Share Rule

  • Pull Deployment Horizon

  • Push Deployment Horizon

  • SNP Checking Horizon

Activities

Heuristic

The PP/DS Deployment heuristic, SAP_PP_024, is based on the /SAPAPO/HEU_PPDS_DEPLOYMENT algorithm. You use this heuristic to define the settings for the deployment horizon and the processing of stock transfers, both of which are described above; in Customizing, choose   Advanced Planning and Optimization   Supply Chain Planning   Production Planning and Detailed Scheduling (PP/DS)   Heuristics   Maintain Heuristics   SAP_PP_024   to carry out these settings.

Deployment Characteristic Profiles

You can maintain PP/DS deployment characteristic profiles within the system. In Customizing, choose   Advanced Planning and Optimization   Supply Chain Planning   Production Planning and Detailed Scheduling (PP/DS)   Deployment   Maintain PP/DS Deployment Characteristics Profile   .
