This is what happens in the video
Running an MRP batch job in Business Central calculates a complete material requirements plan for your items. You run it from either the requisition worksheet or the planning worksheet. The planning worksheet does a little more than the requisition worksheet, so it is the better choice when you need the full picture.
You start the job by selecting Prepare and then Calculate Regenerative Plan. Before running, you can filter on location, items, low-level codes and more, or remove all filters to run for all items at once. Be aware that with many items, high complexity and a large number of demands and supplies, the batch job can become heavy and take a long time to complete.
Where to run the MRP batch job in Business Central
You can run an MRP batch job in two places: the requisition worksheet or the planning worksheet. Both let you calculate planning suggestions, but the planning worksheet offers more functionality. If you want the most complete planning capability, use the planning worksheet.
How to start the calculation
In the planning worksheet, go to Prepare and choose Calculate Regenerative Plan. This opens a set of settings that control how the calculation runs. From here you decide the scope of the plan.
You can run the calculation for all items by removing all filters, or you can narrow it down. The available filters include location, item filters and low-level codes, among others. This lets you target exactly the part of your plan you want to recalculate.
What the batch job actually does
Calculate Regenerative Plan calculates a complete MRP plan. It looks at your demands and supplies and produces planning suggestions for your items. When you run it across everything, you get a full overview of what needs to happen with your items.
Performance and how heavy the job can be
The weight of the batch job depends on your data. If you have many items, a lot of complexity and many demands and supplies, the calculation can become a very heavy batch job that takes time to run. On smaller datasets, such as a demo environment, it runs quickly. Keep this in mind when you plan when and how often to run a full regenerative calculation.
