Perform Planning Network MRP
Explanation
This activity is used to calculate the supply and
demand for MRP (Material Requirement Planning)
parts (including multi-site planned
parts ) based on shop orders, customer orders, etc,
for a particular planning network. Parts that are
sourced from an internal supply site in the planning network will be a
multi-site planned part. (It can be supplied externally as well.) Once the multi-site BOM's
sourcing rules are defined,
multi-site planning can be performed. The multi-site BOMs are defined
regardless of the planning networks. The system
creates MRP planned orders
for fulfilling demands, such as purchase or shop
order requisitions. The system also offers suggestions on planning orders for optimal
manufacturing considering material availability. MRP generates the distribution orders for
the demands on the sites in the planning network. Manufactured and acquired split data in the
Inventory Part/Planning tab window will be considered when creating the supplies by MRP.
Only the sites to which the users has access,
can be added or removed from a
planning network. A planning manager will enter planning network information into the system. Planners and managers
can review this information.
Prerequisites
- The sites for the network must have been defined
- The user allowed sites must have been defined.
- Multi-site planned parts must have been defined.
- BOMs must have been defined for parts, and lead times
must have been established for both purchased and manufactured parts. MRP only uses the existing product structure with
the alternate denoted by an asterisk (*).
- You must have created a master production schedule using IFS/Master Scheduling or
you should run PMRP.
- If you want to perform multi-site MRP processing,
you must first define a planning network in IFS/General Data for Inventory and
Distribution as well as define multi-site planned supplier parts in
IFS/Purchasing.
Note: MRP does not process parts with planning methods B -
Order Point Planning, C - Replenishment Level, M - Manufacturing Cell Part; or N - Next Level Demand.
System Effects
- Different subsets of the planning network can be
planned at different times without losing important plans from the previous
results. For example, MRP will remove unreleased distribution orders that
were previously generated for the demand from the sites in the planning
network. Distribution orders with the demands from the sites outside the planning
network will not be removed.
- After this process is executed, the Warning
or Error status can apply. Error indicates that some critical errors have occurred in the
process, and the MRP process was stopped. Warning indicates that a message posted
for this process has to be reviewed by the user. This can be done by selecting the
View
Detail right mouse button option in the
Background Jobs window, which
displays the message in the status information table. If you decide to
continue the MRP process, the MRP will display error messages when
the process is completed.
- MRP calculation will consider inventory parts where the MRP Control Flag
check
box in
Inventory Part/Manufacturing tab window is
selected.
- MRP will generate shop order requisitions or non-firm production
schedules for parts that must be manufactured, and it generates purchase requisitions for parts that
must be purchased. Shop order requisitions that are not converted into shop orders and
non-firm production schedules are deleted the next time you start the MRP
process. MRP calculates the
lowest level code of parts and updates the Low Level field on the
Inventory
Part/Manufacturing tab.

Planning Network MRP
Procedure
You can execute multi-site MRP either by direct
execution (Procedure A) or by scheduling the task to execute as a background job
(Procedure B).
Procedure A:
-
Open the
Perform Planning Network MRP
window.
-
Enter the planning network for which you want to run
multi-site MRP. Click List to select from the available planning
networks. If you leave the field blank, the MRP process is run for all planning networks
to which you have access.
-
Select the date on which you want the MRP process to execute. The
current date is used by default.
-
Optionally, you can stop the MRP process when any
error occurs.
-
Optionally, you can add 1-day lead-time back-off to
planned receipts.
-
If you do not want to create messages for phantom part
dependant demands, you can select the Don't create messages for phantom part
dependant demand check box.
-
If you want the MRP process to
create safety stock replenishment orders on
the MRP run date, select thePlan
Safety Stock Receipt on MRP Run Date
check box. If it is not selected, safety stock
replenishment orders will be created on the event date itself.
-
If you want the MRP process to capture the planned
alternate
parts, you can do so by selecting the Plan Alternate Components check box.
-
If you want to get the default values defined by the
administrator in the Database Tasks window,
click Default.
-
To run the multi-site MRP process, click OK.
Procedure B:
Click Schedule to open the
New Database Task Schedule window. Set the scheduling parameters as
desired and save. Scheduled tasks can be seen in Scheduled Database Tasks
window
