Use this activity to run an MRP Simulation using real-time supply and demand data from the system, combined with simulated independent demands defined on the Simulation Profile - MRP Parts page, under the Additional Demands tab. You can execute this simulation for a site or a planning network. This method allows you to simulate the impact of potential demand changes on current supply and inventory positions.
If Master Scheduling (MS) top-level parts are present, the simulation begins with the exploded demands to
MRP-planned parts, based on planned receipts already executed for MS level 1 parts within the selected Material
Planning Scenario. It then proceeds to perform MRP and MS calculations for all MRP- and/or MS-planned parts across
the bill of materials, either per site or across a planning network.
If you want to retrieve the latest demands and generate supply proposals for MS top-level parts, you must first
execute the Master Scheduling (MS) calculation for the selected Material Planning Scenario.
The MRP Simulation job is posted as a background job and can either be started now or scheduled for later execution.
As a result of this activity, an MRP simulation is executed using the latest live data along with the simulated independent demands. The results provide a dynamic view of potential planning outcomes, without generating actual planning engine proposals.
