A D V E R T I S E M E N T
You
assign different groups according to the requirements to run MRP (different
Settings). These settings will be taken in account when you run MRP for single
item or total planning.
MRP controller is the person in charge of the MRP run for the
materials. It is still a further division on your MRP. This is work load
related. You can have one MRP controller for materials with different MRP
groups.
On your MRP group, you will define the parameters for the MRP
run. These parameters are calculated in accordance with the settings on your
material master MRP views.
Available stock =
Plant stock - safety stock +
receipts of (purchasing orders + purchasing agreements +
production orders) - required quantity.
This means that all the requirements are calculated in the
bases of your material master settings and your MRP group settings.
What if nothing happens when you run MRP?
The reasons could be :-
- You have purchase requisitions that are delayed but the
delivery time has not been updated on the system.
- The settings on your material MRP screens are not correct,
i.e. your material have not yet
entered the re-order point level.
- Your requirements have not been taken in account when
running MRP.
Assuming that everything is well and the requirement has been
calculated, go to transaction code MD04 and
verify that the different requirements are reflected in the MRP list and also if
there is any purchase requisition scheduled by the system. Verify also if there
is any other delivery schedule that will exceed the actual requirements.
If the purchasing requisition is there, the only thing that
you have to troubleshoot is the message to tell you that the purchasing
requirement was calculated.
If the requirement is not there, re-visit your material
master and check your settings for the MRP group.
