Expand/Collapse item  Overview

You can perform MRP generation to collect data relative to all material needs of manufacturing and distribution, and view recommended actions in the MRP Report.

During the MRP generation process, the system scans the relevant modules, disassembles the bill of materials, and calculates and stores the data in a temporary MRP work file prior to printing any selected reports. For more information, see The MRP Generation Process.

Expand/Collapse item  Before You Begin

  • After the MRP Generation process starts, results from the previous MRP Generation process are deleted. The MRP Report and MRP Inquiry tasks are not available until the new process is completed. The MRP calculations are complex and depending on the amount of data to be examined, can be time consuming; the calculations may take several hours to complete. 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 MRP Generation process so that users do not enter the system after the process begins.

  • To automatically restart the process after an error has occurred, select the MRP Generation on Error Condition check box in the MRP Options window.

 

To generate MRP calculations

  1. Select Material Requirements Planning Main menu > MRP Generation.

  2. If the Bill of Materials module is integrated with MRP and the Enable Engineering Change Control check box is selected in the Bill of Materials Options window, in the Effective Date field, enter the effective date to include all engineering changes made through the date entered. For more information, see MRP Generation - Fields.

  3. In the Default Build/Lead Time (Days) field, enter the default number of days to use as build/lead time.

  4. In the Sales Order Cutoff field, enter a date as the cutoff promise date for sales order line items. The system will disregard any sales order line items with a promise date past this date.

  5. If desired, enter the project demand start and cutoff dates.

  6. Select the MRP reports to print, and click the corresponding button to set up printing selections for those reports.

  7. Select the demand sources to print.

  8. Click Print to begin the MRP generation.

  9. You can print the MRP Report, Action by Vendor Report, and MRP by Job Report immediately after competing the MRP generation process.

During the MRP generation process, MRP scans the relevant modules, disassembles the bill of materials, and calculates and stores the data in a temporary MRP work file prior to printing any selected reports. You can view the recommendations calculated from the MRP generation process on the MRP Report or in the MRP Inquiry window.
