Note 110702 - Palletization data in the material master

Summary

Symptom

There are a maximum of 3 palletization specifications in the material master.
How are palletization instruction 1 and 2 are used?
It seeems that the 3rd palletization instruction is not used.

Additional key words

MLGN, palletization, bulk storage

Cause and prerequisites

Palletization instructions 1 and 2 should be defined in descending quantity. When placing in storage, the system creates full pallets of category 1. The remaining quantity is either of pallet type 2 (remaining quantity <= pallet quantity 2) or a broken pallet of category 2. The following examples illustrates the system behavior:
Example: Palletization 1 --> 10 pc for each E1
                      2 -->  5 pc for each E2

1. The quantity to be placed in storage is smaller than the 2nd palletization specification, the system proposes the 2nd palletization instruction.
Example: Quantity 4 --> 1 x 4 pc for each E2

2. The quantity to be placed in storage is between the first and second palletization instruction, the system proposes the first palletization instruction.
Example: Quantity 7 --> 1 x 7 pc for each E1

3. The quantity to be placed in storage is larger than the first palletization specification, the system splits it and proposes the first palletization specification or a multiple of the quantity and the second palletization for a remaining partial pallet quantity.
Example: Quantity 12 --> 1 x 10 pc for each E1
                        1 x  2 pc for each E2

4. The quantity to be placed in storage is larger than the first palletization specification and a remaining quantity is larger than the 2nd palletization specification, the system splits it and proposes the first palletization specification or a multiple of the quantity and also the first palletization for the remaining quantity.
Example: Quantity 39 --> 3 x 10 pc for each E1
                        1 x  9 pc for each E1

This comparatively simple logic cannot be changed in the standard system for reasons of upward compatibility. However, a user exit (MWMTO007) does exist in which you can implement any algorithms you like.
The 3rd palletizion instruction might be important in the bulk storages since in the material master only defined pallets may be placed in storage, there. For bulk storages not managed in service units the number of storage units is calculated on the location storage via the defined block structures and the found service unit category and the quantity on the block storage bin by means of the palletization specifications in the material master.

Solution

You can implement more complex palletization logics in user exit MWMTO007.
