 Dynamic Route Determination

Use

This function performs automatic transportation planning and scheduling without calling the optimizer. As a result, you get shipment proposals and the relevant dates/times.

The ERP system automatically triggers dynamic route determination when you create or change sales orders. For more information, see Dynamic Route Determination from the ERP System .

You can also perform dynamic route determination interactively for your orders (sales orders, purchase orders, and so on) and deliveries from the planning view of the Transportation Planning/Vehicle Scheduling (TP/VS) component. Simulation and background modes are also available.

Prerequisites

  • You have defined a route determination profile . To do so, on the SAP Easy Access screen, choose Start of the navigation path Advanced Planning and Optimization Next navigation step Transportation Planning/Vehicle Scheduling Next navigation step Environment Next navigation step Current Settings Next navigation step Dynamic Route Determination Next navigation step Define Route Determination Profile. End of the navigation path

  • If you want dynamic route determination to be triggered automatically from the ERP system, the following prerequisites must be met:

    • You are using SAP R/3 Release 4.6C or higher (ERP system).

    • You have installed the Global Availability Check (Global ATP Check) .

    • You have executed the report ATP_BASIC_SETTING in the ERP system, including setting the Retransfer ATP Desired Dates indicator. We recommend that you also set the Group Check w/o Delivery Group and Grp Check with Background EDI indicators to enable the system to check multiple items from a document at the same time.

    • You have activated dynamic route determination for the required order type in Customizing for TP/VS under Start of the navigation path Dynamic Route Determination Next navigation step Activate Dynamic Route Determination. End of the navigation path

    • If you want the system to perform an order split based on freight units , you must choose the relevant area in the split rule .

    • If you want the system to restart dynamic route determination if the required quantity is not available on the required material availability date, you must set the ATP-Conf. Quantities indicator in Customizing for TP/VS by choosing Start of the navigation path Basic Settings Next navigation step Basic Settings for Vehicle Scheduling. End of the navigation path

  • If you want to call dynamic route determination in TP/VS from the planning view or in the background, you have specified the required route determination profile in the optimization profile or have specified that the system is to determine a route determination profile. To do so, on the SAP Easy Access screen, choose Start of the navigation path Advanced Planning and Optimization Next navigation step Transportation Planning/Vehicle Scheduling Next navigation step Environment Next navigation step Current Settings Next navigation step Transportation Optimization Next navigation step Define Optimization Profile (General End of the navigation path tab page) .

Features

Dynamic route determination performs the following steps, for example:

  • Geographical determination

    The system determines shipment proposals for the sales order items on the basis of the following data, for example:

    • Transportation lanes

    • Transshipment locations (a maximum of two)

    • Compatibilities

    • Means of transport (in accordance with your settings in the route determination profile)

  • Assignment of vehicle resources

    The system determines suitable vehicle resources for the shipment proposals. Here the system takes into account the following:

    • Compatibilities

    • Capacities

    • Assignment of vehicle resources to existing shipments

  • Scheduling

    The system performs scheduling on the basis of the following data, for example:

    • Loading resources and resources maintained in opening times

    • Pickup or delivery windows

    • Schedules

    • Minimum or maximum goods wait times at transshipment locations

    • Calendars and working times for vehicle resources

    • Existing shipments

  • Check of transportation allocations of transportation service providers (TSPs)

    The system checks the transportation allocations of the TSPs for the shipment proposals. As a prerequisite, you must have set the TSP Capacity Check indicator in the route determination profile.

    For more information, see Check Against Transportation Allocations .

  • Determination of transportation and penalty costs

    The system determines TSP-dependent costs and TSP-independent costs for the shipment proposals.

    • Determination of TSP-dependent costs

      Here the system takes into account one of the following:

      • APO-internal costs

      • ERP costs

      • Costs that were determined using the Business Add-In (BAdI) /SAPAPO/VS_RG_COST

    • Determination of TSP-independent costs

      The system determines the costs on the basis of the cost profile, for example, costs for earliness or delay. Here the system takes into account the pickup and delivery windows.

SAP delivers these steps, in the sequence specified, in the default strategy 50_DEFAULT with the following methods:

  • 50_DND Dynamic route determination

  • 50_RSEL Resource selection

  • 50_SCHD Scheduling

  • 50_CAPA TSP capacity check

  • 50_CCAL Cost calculation

You can define your own strategies in accordance with your requirements, for example, by deleting steps, adding additional steps, or ordering your steps differently. You define strategies in Customizing for TP/VS under Dynamic Route Determination . You can also use various BAdIs for incorporating customer-specific solutions in Customizing for TP/VS.

Note Note

Dynamic route determination does not support trailers, compartments, or decreasing capacities.
