Perform Selective Project MRP

Explanation

This activity is used to run project material requirement planning (project MRP) for a selected set of part(s) or desired low levels. It could be within a single project or within multiple projects. The application creates project MRP planned orders and offers suggestions for planning orders for optimal manufacturing, considering material availability for the selected set of project planned parts.

The supplies and demands will be calculated by selective project MRP based on project connected demands and supplies along with non-standard planned components. Planning methods B, C, N, O, and T are excluded by selective project MRP.

Prerequisites

• Selective project MRP identifies supplies and demands for project MRP parts generated by customer orders, purchase orders, project master scheduling, shop orders and work orders only if those demands are tagged with PPSA (program, project, sub project and activity).
• To perform selective project MRP across multiple projects, a project planned netting group (PNG) must have been defined.

Selective project MRP requires the following general prerequisites:

• A bill of materials (BOM) must have been defined for the parts, and lead times for both purchased and manufactured parts must have been established. The product structures must be in the Plannable or Buildable status, otherwise the BOM explosion will stop. Selective project MRP only uses the existing product structure with the alternate indicated by an asterisk (*). Parts that are marked as non-standard planned, will be planned by selective project MRP .
• The selective project MRP calculation will consider inventory parts that have the MRP Control Flag check box selected on the Inventory Part/Manufacturing tab.
• Before you can run selective project MRP, you must go through a data set up in Inventory and Purchasing. Calendars must be created and attached to the sites. Basic data must be entered in Manufacturing and the shop order. Since selective project MRP is based on the quantity on hand and planned orders,  selective project MRP will take them in to the calculation only if these supply and demands are project connected.
• PPSA must be in the Released status.
   

System Effects

• A new background job for the selective project MRP process will be started, and it can be queried for in the Background Jobs window.
• After the process is executed, it can get the Error, Warning, or Ready status.
   

• Selective project MRP will generate shop order requisitions for the selected parts that must be manufactured and purchase requisitions for parts that must be purchased for the selected parts. Shop order requisition type and purchase requisition IDs are project MRP. Shop order requisitions that are not converted to shop orders will be deleted in the next project MRP or selective project MRP process.
• Selective project MRP will calculate the lowest level code parts and update the Low Level field on the Inventory Part/Manufacturing tab.
• In the selective multiproject MRP process, when a user specifies a planned netting group (PNG), the system creates a project MRP planned material transfer requisition (MTR). The multiproject MRP process creates material transfer requisitions in addition to shop requisitions and purchase requisitions. MTRs created by the multiproject MRP will not have the MTR Manually Created check box selected.
• When creating MTR, the Generate MTR for Planning Only check box in the Planned Netting Group window determines the type of MTR that will be created by selective project MRP. If the check box selected, selective project MRP will create MTR with the Planning type. If it is not selected, possible MTR types that will be created are: Transfer, Borrow and Payback.
• If the Generate Safety Stock check box is selected in the Project Navigator/Activity List tab, Project Navigator/Activity tab, Activity/General or Activities window, and if the part has safety stock specified in the Inventory Part/Planning Data tab, then safety stock will be generated for this part and activity when running selective project MRP.
• The MRP Part Information window will indicate that the results are based on selective project MRP by the MRP Type field in the header set as Selective PMRP.

Procedure

Procedure A:

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 selective project MRP.
2. Your default site appears in the Site field. Enter the site for which you want to run selective project MRP. Use the List of Values to select from the available sites. Entering a value in this field is required.
3. Enter the ID of the project for which you want to run selective project MRP in the Project ID field. (If you enter the wildcard (%) or leave the field blank, selective 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 selective project MRP. (If you enter the wildcard (%), 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 selective project MRP. The current date is used by default.
6. If you want to stop the selective 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 do not want to create messages for phantom part dependent demands, select the No message for phantom part dependent demand check box.
9. If you want the selective project MRP process to create safety stock replenishment orders on the selective 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 selective 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 selective MRP after selective project MRP is completed, select the Start MRP Process once PMRP is completed check box.
12. Select the Run Integrated with CRP check box in order to use the CRP backward scheduling logic to schedule the shop order requisitions generated from the process. If the Run Integrated with CRP check box is selected, CRP backward scheduling logic will be used to schedule shop order requisitions generated from the process. As a result, the start date of the requisitions/receipts generated will be more accurate.
13. If you want to get the default values defined by the administrator in the Database Tasks window, click Default.
14. To perform a selective project MRP, click Selection and open Selective Project MRP Run Criteria dialog box. Selective project MRP will enable you to run project MRP for the selected set of parts from the site specified in step 2. Use this dialog box to specify the selection criteria. You can use wildcard characters in these fields. If you enter multiple selection criteria, parts that fulfill all the conditions will be selected to run the selective project MRP. If you want to run selective project MRP for low levels (for example 3) then use 3 in low level code field and run project MRP. Then analyze the results and do the necessary adjustments to level 3 results. Run project MRP for low level 3..4 (entering 3..4 in low level code field) again to plan the next level and continue the process up to the level you want.
    
    Note: It is advisable to perform selective project MRP for low levels without any other selection criteria. For example, even though running selective MRP for low level code n..n+1 only for the product family PF1 will yield correct results, but result would look like confusing. So planner has to be cautious when analyzing the results.
15. Click OK.

Procedure B:

1. Open the Perform Project MRP per Activity, Perform Project MRP per Project PNG or Perform Project MRP per PNG dialog box.
2. To perform a selective project MRP, click Selection and open Selective Project MRP Run Criteria dialog box. Selective project MRP will enable you to run project MRP for the selected set of parts from the site specified in step 2. Use this dialog box to specify the selection criteria. You can use wildcard characters in these fields. If you enter multiple selection criteria, parts that fulfill all the conditions will be selected to run the selective project MRP. If you want to run selective project MRP for low levels (for example 3) then use 3 in low level code field and run project MRP. Then analyze the results and do the necessary adjustments to level 3 results. Run project MRP for low level 3..4 (entering 3..4 in low level code field) again to plan the next level and continue the process up to the level you want.
3. Click Schedule to open the New Database Task Schedule window.
4. Set the required scheduling parameters and save. Scheduled tasks can be seen in the Scheduled Database Tasks window.

Note: If the corresponding inventory part is a project master schedule planned part, then selective project MRP will not plan the part and components. First you need to run master scheduling and then right-click and execute Run Project MRP for components from MS Level 1 window.
