To optimize processes in the warehouse, it often makes sense to split up putaways and stock removals into smaller packets according to certain criteria. In doing so, it is important, for example, to:
The transfer order (TO) represents a work package and determines the actual workload for a putaway or stock removal. It can therefore make sense to split a single, extensive transfer order into several smaller transfer orders. During the TO split, the system creates several smaller packets from one large one.
During the TO split, the TO items are divided up between one or more TOs. A TO split does not however mean that the system divides individual items of a TO into smaller TO items.
In the sort profile for the TO, you define the criteria according to which you want to sort the items in a transfer order before the actual split.
For each of these sort criteria, you define whether the system is to sort the transfer order items in ascending or descending order.
Before the actual dynamic TO split, you must sort the corresponding TO according to certain criteria. By sorting the TO items, you ensure that the TO split is sensibly executed and that no nonsensical TO splits occur.
You also assign a key to the TO split profile, consisting of a warehouse number, movement type, source storage type and destination storage type.
Standard Sorting of TO Items
Control of the TO split occurs on the basis of the sort. The system defines the sequence of the items in the transfer order before the actual TO split via the sort, so that the sequence of the TO items corresponds to an optimal sort sequence for later processing.
Since the system always executes the forced split of the transfer order items according to the forced split criteria, the system always sorts the TO items in the standard sort in accordance with the forced split criteria in the order that the forced split criteria are processed.
Even if you have not set any user-defined criteria for the TO split, the system always executes a TO split according to the following forced split criteria:
The TO split first divides the TO items for which planned data creation is required, from the TO items for which planned data creation is not required.
The TO split also causes a further division for all TO items with planned data creation, according to the source storage type and destination storage area criteria.
As soon as TO items differ from one another in the split profile to which they are assigned, a TO split occurs according to the split profile criterion.
As soon as TO items differ from one another in the performance data profile to which they are assigned, a TO split occurs according to the performance data profile criterion.
The TO split divides the TO items according to the staging zone to which they are assigned.
The TO split then separates the TO items containing mixed pallets from those containing no mixed pallets.
The TO split also creates a further division of all TO items with mixed pallets according to the storage unit that is to be moved.
The TO split divides the TO items according to the queue that these TO items are assigned to.
If you work with queues, you can assign each work area to its own printer. That way, all materials that are to be processed in a specific area can be combined in one list and printed on the assigned printer.
The TO split then separates the TO items containing handling units from those containing no handling units.
The TO split divides the TO items with split confirmation from TO items for which split confirmation is not planned.
The system transfers the information on the forced split to the header via the transfer orders, which are created as a result of the TO split.
The forced split criteria are obligatory. You cannot influence the forced split via the user exit. The system does not adopt any changes to the forced split criteria.
Before you can execute a dynamic TO split controlled via the Customizing settings, the TO items should be sorted according to the split criteria. In doing so, you ensure that the TO split is sensibly executed and that no nonsensical TO splits occur.
You can define the sequence of all the storage bins in the warehouse based on a specific sequence and sort the TO items according to this sequence. The system sorts according to the Sequence indicator in the warehouse master data.
You can define several criteria for the TO split in the Customizing for Warehouse Management.
On the basis of this split criterion, you create a new TO for each movement unit. In doing so, you create TOs with one item for exactly one movement unit.
You use this split, for example, during goods receipt when a whole pallet is moved from the GR area into the warehouse.
You define the split according to movement unit in the Customizing for Warehouse Management under Activities
You divide up the items to be picked according to the areas of responsibility of the picker.
You determine, for example, how long the picking for a transfer order is allowed to take.
You determine the total weight or volume that a transfer order can cover for putaway or stock removal.
Note that the volume is calculated based on the alternative unit of measure. A box with 10 bottles, for example, can have a different volume than 10 times the volume of one bottle. If the volume for the alternative unit of measure has not been defined in the material master record, the system uses the volume from the base unit of measure for its calculation.
Note that you have no influence over the TO split according to forced split criteria.
You can, however, define your own criteria for a dynamic TO split via user exit MWMTO012. For more information, see the system documentation on this user exit.
