 Aggregated Planning

Purpose

Aggregated planning in Supply Network Planning (SNP) supports planning scenarios in which you carry out heuristic-or optimization-based planningat header location product level of a location product hierarchy. You then disaggregate the planning result to the individual sub products of this two-level hierarchy. You might want to use this type of planning to:

  • Improve performance

  • Simplify the planning process

  • Simplify the supply chain model to be planned (option of planning large models)

  • Make planning decisions at aggregated level (for example, selecting sources of supply, considering capacities, or defining lot sizes)

After the SNP planning run and SNP disaggregation , you can display and change the data in interactive Supply Network Planning. You can also display the resource consumption at header product and sub product level and run capacity leveling for the resources of the sub products in the capacity view of interactive planning.

Prerequisites

See Prerequisites for Aggregated Planning .

Process

An example of a process for aggregated planning is given below. It is assumed for this process that you are planning interactively. From the SAP Easy Access screen, choose Start of the navigation path Supply Network Planning Next navigation step Planning Next navigation step Interactive Supply Network Planning (all Books). End of the navigation path Then choose planning book 9ASNPAGGR and data view SNPAGGR(1). For more information about interactive Supply Network Planning, see Interactive Supply Network Planning Desktop .

You can also run the SNP heuristic, SNP optimizer, and SNP disaggregation in the background. You can then view and change the results in interactive Supply Network Planning.

  1. Aggregated Safety Stock Planning

    You carry out safety stock planning based on aggregated data. This process step is optional. For more information, see Aggregated Safety Stock Planning .

  2. Single-Level Supply and Demand Mapping

    You execute a single-level assignment of distribution receipts and demands at sub product level. This process step is optional. An assignment at sub product level can prevent the system from making incorrect assignments at header product level at a later time.

    For more information, see Single-Level Supply and Demand Mapping .

  3. Aggregation of Demand Data

    In the interactive SNP shuffler, you select the header location product for which you want to carry out planning. The aggregated demand values for the header location product are then displayed in the demand key figures, such as Forecast or Customer Requirements . The demand values of the sub products are automatically aggregated to a total value for the header product in these key figures (depending on the aggregation indicator; see Prerequisites for Aggregated Planning ). The values remain at sub product level, which means, if you choose a sub product, the value for this product is displayed in the key figure. Furthermore, a macro aggregates the opening stock for the header location product and displays it in the initial column of the Stock on Hand key figure.

    If the unit of measure of the sub products differs from that of the header product, the system converts the product unit of measure into the header product unit of measure during aggregation.

  4. SNP Planning Run at Aggregated Level

    You perform an SNP heuristic or optimization run for the header location product. The header location product planning results are then stored and displayed in the Distribution Receipt (Planned), Distribution Demand (Planned), Production (Planned) and Dependent Demand key figures.

    Before creating new orders during the planning run, the system first deletes all the planned orders from outside of the SNP production horizon and extended SNP production horizon, and all SNP stock transfers outside of the SNP stock transfer horizon that were created but not fixed in previous planning runs. It deletes the orders at header product level and at sub product level (depending on the setting in SNP Customizing; see Prerequisites for Aggregated Planning ).

  5. Disaggregation of Planning Data

    You perform SNP disaggregation for the header location product. That means you disaggregate the planning result for the header location product over the sub products. For more information, see SNP Disaggregation .

    After disaggregation, the system transfers the aggregated values to the Aggregated Distribution Receipt or Aggregated Distribution Demand (Planned) key figures and to the Aggregated Production (Planned) or Aggregated Dependent Demand key figures. To display the values, select the header location product. The disaggregated values for the sub products are displayed in the non-aggregated key figures, such as Distribution Receipt (Planned) , and so on. For this, select a sub product. In addition, you can display and change the individual orders for the sub products of the header product in the detail view for the aggregated values.

  6. Display of Resource Consumption

    You can display the effects of planning on resource consumption in the capacity view of interactive planning. Here, you can drill down the header location product and display the resource consumption for this product in the upper table.

    The resource consumption at header location product level is the total of the resource consumption of the sub products and the resource consumption of the header product. That way you can see the resource consumption at header product level before and after SNP disaggregation. The prerequisite for this is that you are using a resource hierarchy or the same resource at header product and sub product level.

    In the lower table, you can also display the product quantities for all PPMs or PDSs that belong to the selected header location product and use the selected resource. For this, choose Display dependent objects and then choose PPM/PDS .

  7. Capacity Leveling

    If necessary, you can then run capacity leveling for the resources of the sub products.

    For more information, see Capacity Leveling .

  8. Change Data at Header Level

    If you want to change the data for specific header location products after an aggregated SNP planning run and disaggregation, you can run aggregation again for the planned orders and stock transfer orders created by SNP. Afterwards, you can disaggregate the changed data again.

    For more information, see SNP Aggregation .
