Function documentationMRP Live: Control Parameters

 

You use the control parameters to determine how the planning run is to be executed and which results are to be produced.

Features

The following features are available:

  • Regenerative Planning

    If you select this checkbox, the system plans all plant materials irrespective of whether they have been changed in some way relevant to planning since the last planning run. If you leave this checkbox empty, the system executes a net change planning meaning that only the materials that have been changed in some way relevant to MRP since the last planning run are included in planning.

  • Scheduling

    Determines whether the system is only to calculate basic dates for planned orders, or whether you also want to perform lead time scheduling. You have two options for scheduling:

    • 1: Determination of Basic Dates for Planned Orders

      The system also assumes this entry if you leave this field blank. That is, if no entry exists here the system only calculates basic dates for planned orders.

    • 2: Lead Time Scheduling and Capacity Planning

      With this setting, the system performs lead time scheduling for planned orders. This includes all planned orders that are new or have been changed or have been re-exploded for the BOM. The system will continue to use lead time scheduling in the future for planned orders that have already undergone lead time scheduling, even if you change this setting back to 1. If, however, you carry out the planning run using planning mode 3 and scheduling mode 1, the system deletes all planned orders that are not yet firmed and creates new ones with basic dates.

      In lead time scheduling, the system calculates the precise production times, that is, the production start date and the production finish date for materials that are produced in-house. Capacity requirements are also created and the date on which the components must be provided is determined.

    For more information on scheduling, see Scheduling.

  • Planning Mode

    The planning mode controls how the system is to deal with procurement proposals (planned orders, purchase requisitions, scheduling agreement lines) from the last planning run that are not yet firmed in the next planning run. You have two options to define the planning mode:

    • Planning Mode 1: Adapt Planning Data

      If the system finds an unfirmed procurement proposal that completely matches a requirement, it reuses this procurement proposal. If the system finds an unfirmed procurement proposal that only partially matches a requirement (for example, the quantity is correct but the date does not suit the requirement), the system deletes this unfirmed procurement proposal and creates a new one. The system explodes the BOM again for the recreated procurement proposals.

    • Planning Mode 3: Delete and Recreate Planning Data

      The system deletes all unfirmed procurement proposals and creates new procurement proposals to match the requirement situation.

    For more information on planning modes, see Planning Mode in the Initial Screen.

  • Name for Performance Log

    You can define the name of the file under which you can find the performance results of the MRP Live run in the MRP Live Performance Log report. You can enter a name of your choice.

    In the initial screen of the MRP Live Performance Log report, you can then call up a list of all the MRP Live runs that were carried out for this name to compare the results.
