Load Building

Purpose

Load building is used to:

  • Minimize transport costs by making best possible use of the means of transport (for example, ship, rail freight container, truck)

  • Minimize the merchandise in the warehouse by placing a purchase order at the latest possible moment.

  • Achieve the best purchase prices, for example, by ordering complete truck loads.

To this end, if possible, SAP Retail optimizes quantities for procurement, converts existing purchase requisitions to purchase orders, groups purchase orders together and, if necessary, also generates new purchase orders (for example, if the range of coverage is increased). Several purchase orders are combined using a collective number.

Load building can be run automatically or manually. Both methods differ in terms of the prerequisites that apply and the functions that are available. They can also be used in different combinations:

  • You allow the system to simulate automatic load building and you then manually convert the result in the results list (if necessary, without the purchase order being flagged as optimal through the assignment of a collective number) to purchase orders.

  • You always allow the automatic load building program to generate purchase orders. You can optimize and flag optimized purchase orders (achieved by assigning a collective number) further in manual load building.

  • You only allow load building to create purchase orders when the system can flag the purchase order as optimized. You optimize quantities using the automatic load building program. You only use manual load building in cases where the automatic load building program cannot find an optimal solution.

    Note Note

    When performing calculations, load building does not take into account scales, free-goods discounts, and target quantities and values defined in contracts. For example, although the target quantity in a contract is 50 boxes and the target value is 10,000 euros, these restrictions will be exceeded if the load building calculation for the range of coverage results in higher quantities.

    Note Note

    The following special cases are only of minor importance in load building or cannot always be completely valuated when load building is performed:

    • Achieving better scaled conditions

    • Discounts such as free-goods discounts

    • Additional packaging

    • Reduced packaging

    As a result, and due to the impact this would have on performance, the system does not take these factors into account.

    End of the note.

    Note Note

    If you use load building, you should also use forecasting so that the system can calculate the range of coverage of the stock and determine the additional items and quantities required. You have to decide which forecasting method to use for each combination of article and site.

    For more information on this topic, see MM – Consumption-Based Planning: Forecast Parameters .

    End of the note.

    Note Note

    Load building is based on the purchase requisitions and purchase orders created in requirements planning. You have to decide which planning method to use for each combination of article and site.

    Alternatively, you can configure the control parameters for automatic load building so that instead of accessing existing requirements elements, the system generates requirements directly from the forecast values.

    For more information on this topic, see Requirements Planning .

    End of the note.

    Note Note

    For many articles, it is better to place orders in a larger logistical unit (such as 3 pallets) rather than forecasting your exact requirements in the base unit of measure (such as 288 pieces). In this case, you should use dynamic rounding profiles. Rounding profiles make it easier for you to fulfill restrictions, for example, to fill an entire truckload. You have to decide how to define your rounding profiles and to which unit of measure the system should round off the quantities.

    For more information about this topic, see Dynamic Rounding Profiles .

    End of the note.

    Note Note

    When you implement load building, you should begin with a smaller selection of vendors and one distribution center to gather initial experience with the effects of load building. You can then include further vendors and distribution centers as time goes on.

    Decide on the vendors and distribution centers for which you want to use load building. You can use vendor sub-ranges as splitting criteria for purchase orders. The system then optimizes documents for each vendor subrange.

    End of the note.

Prerequisites

  • To use this function, you require SAP ERP configured as SAP Retail , and you must activate the enterprise extension Retail .

  • The vendor for whom the system is to perform order optimizing is an external vendor.

  • You have assigned a restriction profile to the vendor, with information on the minimum and maximum loading capacity for the means of transport used.

    Example Example

    A truck must transport a minimum load of 300 kg, but can only carry a maximum of 27 pallets.

    End of the example.

    You can edit restriction profiles in the Customizing for Materials Management under Start of the navigation path Purchasing Next navigation step Order Optimizing Next navigation step Load Building End of the navigation path .

  • Dimensions, weights, and volumes are available in the master data for the articles (see Articles: Basic Data ).

  3. Using additional quantities to enhance purchase orders that have not been optimized

    See Additional Planning

Variant 4

  1. Creating purchase orders manually

    See Creating a Purchase Order Manually (Vendor Known)

  2. Controlling purchase orders, optimizing by combining several purchase orders and flagging the optimized purchase orders by assigning a collective number

Result

Purchase orders that fulfill all restrictions are bundled logically through the assignment of a collective number and are flagged as optimized.
