WM: New Capacity Checks in the WM System
Description
In addition to the existing capacity checks in the system, there are three new possibilities to control the storage of materials in a storage bin that is based on a neutral indicator.
The basic prerequisites for the new capacity check include the
following:
- Each storage bin must have a dimensional and "unit-less" capacity
- Each material must use a specific capacity for each
unit of measure
- Each storage unit type must have a specific capacity for each storage unit
Based on these prerequisites, there are three new capacity checks:
All three capacity checks can also be used for storage situations, whereas each storage unit counts as a SUT in SU-managed storage types and each quant counts as a SUT in non-SU-managed storage types.
Since it is dependent upon the quantity of the material, the capacity usage of a material is characterized as a variable in the system. It is updated in the quant . The capacity usage of a SUT is characterized as a constant capacity usage and is updated in the storage unit in SU-managed storage types and in the quant in non-SU-managed storage types.
Data from quants and storage units are updated for each storage bin as a remaining capacity. This remaining capacity is recorded in the empty bin index. This makes it possible (for example, using a customer exit) to make an efficient search for an occupied storage bin with a specific remaining capacity.
Example
The following examples correspond to the three new capacity checks. For
these examples, the following conditions apply:
- Material 4711 is managed in the standard unit of measure "pieces" and has
a capacity usage of 11 per piece.
- Storage Bin 01-01-01 has a capacity of 100.
- SUT E1 has a capacity usage of 12.
Nine pieces of material 4711 can be stored in storage bin 01-01-01. This leaves a remaining capacity of 1. This capacity check is meaningful if you can stack materials as desired into this storage bin. It could also replace capacity checks 2 and 3 if there are different batches that result in mixed storage.
Eight full E1 pallets can be stored in storage bin 01-01-01. This leaves a remaining capacity of 4. This capacity check is meaningful when the pallets are next to each other and the materials can be removed one at a time from each pallet.
Eight pieces can be stored in storage bin 01-01-01 on an E1 pallet. This leaves no remaining capacity for the bin. If the material is stored in the bin with one piece per E1 pallet, 4 pallets will fit in the bin (44 + 48) and a remaining capacity of 8 exists. This capacity check is meaningful if the pallets are stacked on top of each other and the thickness of the pallet must be taken into consideration.
Change system parameters in customizing
You can define the new capacity checks in the Customizing application.
Define capacity checksFurther notes
Caution: Before you make the first placement, define the type of capacity check and the capacity usage of material and storage unit types. Changes that are made to these parameters afterwards cause automatic changes to storage bins, storage units and quants. If you make changes in the operational system, you must run report RLS10200 to adjust the occupied capacities for bins, storage units and quants.
