Perform Project MRP

Explanation

This activity is used to perform project material requirements planning with a single project (project MRP) or with multiple projects (multiproject MRP). The application creates project MRP planned orders and offers suggestions for planning orders for optimal manufacturing, considering material availability.

Part requirements can be ascertained based on the sources of supply and demand such as shop orders or customer orders. If project MRP was performed previously, then all the planned supplies and action messages generated in the previous process will be removed first. The results of project MRP suggest a process for fulfilling the demands using, for example, purchase or shop order requisitions. These results also suggest how to plan orders for optimal manufacturing in view of material availability. Project MRP plans the supply for all the parts with a dependent demand. The product or recipe structures of the parts must have been entered. After the structures are entered, you can run project MRP for all the parts with a dependent demand. Project MRP considers only company-owned stock and activity specific requirements. Planning methods B, C, N, O, and T are excluded by project MRP.

Procedure

  1. Open the Perform Project MRP per Activity, Perform Project MRP per Project PNG or Perform Project MRP per PNG dialog box depending on the way you want to perform project MRP.
  2. Your default site appears in the Site field. Enter the site for which you want to run project MRP. Use the List of Values to select from the available sites. Entering a value in this field is required.
  3. In the Project ID field, enter the ID of the project for which you want to run project MRP. (If you enter the wild card (%) or leave the field blank, project MRP is run for all open projects under the specified site).
  4. In the Planned Netting Group field, enter the ID of the PNG for which you want to run project MRP. (If you enter the wild card (%), the system will process all PNGs belonging to the specified site).
  5. In the Run Date field, enter the date on which you want to run project MRP. The current date is used by default.
  6. If you want to stop the project MRP process if an error occurs, select the Stop PMRP on Error check box.
  7. If you want to add a day's lead-time back off to the planned receipts, select the Add 1 day Lead Time check box.
  8. If you want to create messages for phantom part dependent demands, select the Phantom Part Dependent Demand check box.
  9. If you want the project MRP process to create safety stock replenishment orders on the project MRP run date, select the Plan Safety Stock Receipt on PMRP run Date check box. If it is not selected, safety stock replenishment orders will be created on the event date itself.
  10. If you want to exclude PPSAs defined in any PNG when performing project MRP (not multiproject MRP) and when using the Perform Project MRP per Activity dialog box, you have the option of selecting the Exclude PPSAs grouped under any PNG check box.
  11. If you want to start MRP after project MRP is completed, select the Start MRP Process once PMRP is completed check box.
  12. If you want MRP to include alternate components in the planning calculation, select the Plan Alternate Component check box. This will be enabled only after selecting the Start MRP process once PMRP is completed check box.
  13. Click OK.
