Generate IRP Calculations

You can perform IRP generation to collect data relative to all material needs of manufacturing and distribution, and then view recommended actions.

Tip: The IRP calculations are complex and depending on the amount of data to be examined, the calculations can be time consuming and take several hours to complete. You can apply filters to reduce the amount of data calculated. In addition, entering, deleting, or modifying data during the process will either be disregarded, produce incorrect results, or cause errors that will interrupt the process. You should establish guidelines and schedules for running the IRP Generation process so that users do not enter the system after the process begins.

To generate IRP calculations

  1. Select Inventory Requirements Planning > Main > Inventory Requirements Planning.
  2. Enter a selection setting, or use the STANDARD setting.
  3. Select a plan by option and a procurement type option. For more information, see Inventory Requirements Planning.
  4. Enter the cutoff date that represents the end of the planning period.

    Note: Items with a promise date or required date that exceeds the cutoff date are not selected when you generate the data.

  5. If the Inventory Requirements Planning module is integrated with Production Management, and the Base Effective Date on Release Date of Demand check box is cleared in Inventory Requirements Planning Options, enter the effective date to determine component requirements for all bills.
  6. At Options, make selections to determine if lead time, open work tickets for parent items, and sales quotes are included, and select an option at the Explode Make Action field. For more information, see Inventory Requirements Planning.
  7. If desired, select to include projected demands in the generated data, and enter starting and ending dates for the projected demands.
  8. At Selections, select the filters to apply to the data, and then click Generate.

You can view the recommendations calculated from the IRP generation process by clicking Production or Purchase. In Items to Produce or Items to Purchase, view summary information about the demand. Then select a row and click the Item Detail button to view additional supply and demand information.

You can also view the recommendations on the Inventory Requirements Planning Report or in Inventory Requirements Planning Inquiry.
