SAP MRP - Generating Planned Orders for Equalt Quantites NOT exceeding the Max. Lot SIze.

Dear Experts,

Your help reagrding the following problem would be much appreciated.

I am working for a consumer goods company who use multi-level production BoM's. APO sends in the finished goods order into SAP and the lower level semi-finished items are plan using MRP withi R/3.

The problem that I want to overcome is how, based upon a dependant quantity create multiple procurement proposals (inhouse procurement) i.e. planned  orders that are of equal size, but not exeeding the maximum lot size for the order.

For example, 5,000 Kg of the FG is required. This in turn requires 5,000 kg of the semi finished material which is made in mixes. The maximum mix size is 1,500 Kg. The plant wants MRP to generate 4 palnned orders of 1,250 Kg and NOT 3 orders for 1,500Kg and 1 for 500 Kg.

Any help would be much appreciated.

Not sure, but this sounds like a business logic issue that may require programming into the internal order syste.

IE, you will need to know what the max size is for each Item, and use that when creating orders.

I hope this helps !

Best bet would be to ask someone with a good working knowledge of the PP module. Alternatively (I cannot find this information easily myself), open a case with SAP and ask them if this is possible, they'll usually advise a solution. Ok, so sometimes their idea of a solution is 3 days of remote consulting, but at least you get the job done..... So the quitesion then becomes: Do you want it DONE or do you want to DO it ?

Thanks for you assistance SysExpert & Twisteddk:

I think we'll have to solve this by using lot sizing rules for the higher level materials to ensure that when MRP calculates the dependant requirements of the lower level semi-finished materials they are consistant with full mix sizes. This may not be the optimal solution for the business, however, there is no appetite to spend money on resolving this, so it could mean that the planners need to do lots of manual maniuplations of the orders.
