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 option
enabled 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 page.
- After the process is executed, it can get the Error, Warning, or Ready status.
| Status |
Significance |
| Error |
Some critical errors have occurred. Selective project MRP stops the process. |
| Warning |
A message posted for this process has to be reviewed by the user. This can be done by
right-clicking and then clicking Show Details in the Background Jobs page, which displays the posted
message in the status information table. If the user decides to continue the selective project MRP process
when an error occurs, the system will post a message containing a warning. |
| Ready |
The process has been completed successfully without any errors. |
- 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 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 have the Manually Created value is set to no.
- When creating MTR, the Generate MTR for Planning Only option in the Planned Netting Group page
determines the type of MTR that will be created by selective project MRP. If the option is enabled, selective
project MRP will create MTR with the Planning type. If it is disabled, possible MTR types that will be
created are: Transfer, Borrow and Payback.
- If the Generate Safety Stock option is enabled in the Activity Setup Parameters page, and if the part
has safety stock specified in the Inventory Part Planning Data page, then safety stock will be generated for this
part and activity when running selective project MRP.
- The MRP Part Information -Top Down page and MRP Part Information
-Bottom Up page will indicate that the results are based on selective project MRP by
the MRP Type in the header set as Selective PMRP.
