MRP doesn't consider PM Orders and reservation

Hi experts.

I've a prob. When MRP runs the purchase requisiton is created with the quantity based in reorder-point and min. lot size, doesn't matter manual reservations or pm order reservation. The material has mrp at storage location level.

E.G.

SCENARIO #1
Material A
I Tried the MRP types: VB, VM, VV, ND. 
I Tried the Avaliable Check: 01,02,CH, DR,KP
Plant P
Storage S
Reorder point 5un
Safety stock 2un
Actual Stock at sLoc 3.

Mrp created the PREq with 2UN ( Reorder point 5un - Actual Stock at sLoc 3).

SCENARIO #2
Material A
I Tried the MRP types: VB, VM, VV, ND. 
I Tried the Avaliable Check: 01,02,CH, DR,KP
Plant P
Storage S
Reorder point 5un
Safety stock 2un
Actual Stock at sLoc 3.
PM Order Reservation 10un

Mrp created the PREq with 2UN ( Reorder point 5un - Actual Stock at sLoc 3). Whatever many reservations has.

What mrp settings must be done?

Thanks for any help.

Regards.

Hi,

You can control the behaviour of the system via settings of the MRP type.

SPRO > Production > MRP > Master Data > Check MRP Types

This should be set for the MRP type you use:

V438A-ICBED = "2"

On "Additional External Requirements in reporder point planning" tab you can set which requirements shoudl be considered. As default manual reservations and SOs are considered by system as per SAP online help:

http://help.sap.com/erp2005_ehp_04/helpdata/EN/37/8bbbd26a8111d3b4ed0004ac160649/frameset.htm

For PM orders you should mark check-box V438A-A2BED. Please try it...

Regards,

Csaba
