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.
