Perform Project MRP
Explanation
This activity is used to perform project material requirements planning with a single
project (project MRP) or with multiple projects (multiproject MRP). The application creates
project MRP planned
orders and offers suggestions for planning orders for optimal manufacturing,
considering material availability.
Part requirements can be ascertained based on the
sources of supply and demand such as shop orders or customer orders. If project MRP was
performed previously, then all the planned supplies and action messages
generated in the previous process will be removed first. The results of project MRP
suggest a process for fulfilling the demands using, for example, purchase or
shop order requisitions. These results also suggest how to plan orders for
optimal manufacturing in view of material availability. Project MRP plans the supply
for all the parts with a dependent demand. The product or recipe structures of
the parts must have been entered. After the structures are entered, you can run
project MRP for all the parts with a dependent demand. Project MRP considers only
company-owned stock and activity specific requirements. Planning methods
B, C, N, O, and T are excluded by project MRP.
Prerequisites
- Project MRP identifies supply and demand for project MRP parts generated in
the following IFS modules: IFS/Customer Order, IFS/Purchasing, IFS/Project
Master Scheduling, IFS/Shop
Order and IFS/Work Order only if those demands are tagged with PPSA.
- To perform multiproject MRP, a planned
netting group must have been defined in IFS/Project.
Project MRP requires the following general prerequisites:
- 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. Project MRP
only uses the existing product structure with the alternate indicated by an
asterisk
(*).
- 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 project MRP, you must go through an
extensive set up in the IFS/Inventory and IFS/Purchasing modules in IFS
Distribution. You must create calendars and attach them to the sites. You must
have entered basic data in IFS Manufacturing and the IFS/Shop Order.
Since project MRP is based on the quantity on hand and planned orders, data must be
available in these components.
- In addition to the basic requirements for project MRP as discussed above, customer orders, shop orders, and purchase orders for these
parts need to exist. There is much additional information that affects project MRP, and
it is important that you verify this information and its accuracy before running
any calculations.
- Inventory parts with the DOP supply code are managed within DOP.
- Project MRP calculation will consider inventory parts with a part
that allows demand and supply.
- PPSA must be in the Released status.
System Effects
- A new background job for the 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.
Status |
Significance |
Error |
Some critical errors
have occurred. 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 View Detail in the
Background
Jobs window, which displays the posted message in the status
information table. If the user decides to continue
the project MRP process when an error occurs, the system will post a message
containing a warning. |
Ready |
The process completed successfully without
any errors. |
- The project MRP will generate shop order requisitions for the
parts that must be manufactured and purchase requisitions for parts that
must be purchased. Shop order requisition type and purchase requisition IDs
are projectt MRP. Shop order
requisitions that are not converted to shop orders will be
deleted in the next project MRP process.
- The project MRP will calculate the lowest level code parts
and update the Low Level field on the
Inventory Part/Manufacturing
tab.
- In the 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 project MRP. If the check box selected, 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
Project
Navigator/Activity List, Project
Navigator/Activity,
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 project MRP.

Procedure
- 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 project MRP.
- Your default site appears in the
Site field. Enter the site for which
you want to run project MRP.
Use the List of Values to select from the available sites. Entering a value in
this field is required.
- In the Project ID
field, enter the
ID of the project for which you want to run project MRP.
(If
you enter the wild card (%) or leave the field blank, project MRP is run for all
open projects under the specified site).
-
In the Planned Netting Group field, enter the ID of the PNG for which you want
to run project MRP. (If you enter the wild card (%),
the system will process all PNGs belonging to the specified site).
- In the Run Date
field, enter the date on which you want to run project MRP. The
current date is used by default.
- If you want to stop the
project MRP process if an
error occurs, select the Stop PMRP on Error check box.
- 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.
-
If you want to create messages for phantom part
dependent demands, select the Phantom Part Dependent
Demand check box.
- If you want the
project MRP process to create safety stock replenishment orders on
the 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.
- If you
want to
exclude PPSAs defined in any PNG when performing 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.
- If you want to start MRP after
project MRP is completed,
select the Start MRP Process once PMRP is completed check box.
- If you
want MRP to include alternate components in the planning calculation, select
the Plan Alternate Component check box. This will be enabled only
after selecting the Start MRP process once PMRP is completed check
box.
- Click
OK.
