Capacity Check 
Use
In the case of some putaway strategies, it is useful to perform a capacity check for the storage bin when searching for a suitable storage bin. If you have activated the capacity check, the system checks whether the selected storage bin can accept the quantity to be put away when it creates a warehouse task (WT).
Prerequisites
· You can set up the capacity check in Customizing for Extended Warehouse Management (EWM) under Master Data ® Define Storage Type (Putaway Control, Capacity Check field). By default, the checks are predefined in accordance with weight and volume.
· To control the capacity check in accordance with weight or volume, you have defined the following:
¡ You have defined the weight or volume consumption for each storage bin. To do so, on the SAP Easy Access screen, choose Extended Warehouse Management ® Master Data ® Storage Bin ® Create Storage Bin (Stor. Bin tab page, Weight Usage or Volume Usage field).
¡ You have defined a weight or volume consumption per unit of measure for each product in the product master. To do so, on the SAP Easy Access screen, choose Extended Warehouse Management ® Master Data ® Product ® Maintain Warehouse Product (Units of Meas. tab page).
· To control the capacity check in accordance with the capacity key figure, you have defined the following:
¡ You have defined a capacity that is independent of a dimension or a unit for each storage bin. To do so, on the SAP Easy Access screen, choose Extended Warehouse Management ® Master Data ® Storage Bin ® Create Storage Bin (Stor. Bin tab page, Capacity Usage field).
¡ You have defined a capacity consumption per unit of measure for each product in the product master. To do so, on the SAP Easy Access screen, choose Extended Warehouse Management ® Master Data ® Product ® Maintain Warehouse Product (Units of Meas. tab page, Capacity Consumption field).
¡ You have defined a capacity consumption per unit of measure for each packaging material in the product master. To do so, on the SAP Easy Access screen, choose Extended Warehouse Management ® Master Data ® Product ® Maintain Warehouse Product (Units of Meas. tab page).
Features
Extended Warehouse Management (EWM) can check the capacity of a storage bin using the following factors:
· Weight
The system checks the weight of the product to be put away against the available weight of the storage bin.
· Volume
The system checks the volume of the product to be put away against the available volume of the storage bin.
· Capacity key figure (see below)
¡ Capacity check in accordance with product
This capacity check is recommended if you can stack products in the storage bin in any way you like. You can also apply this capacity check if different batches of the product exist that result in mixed storage.
¡ Capacity check in accordance with handling unit (HU)
This capacity check is recommended if the HUs lie next to one another and you can remove the products one after another from each container.
¡ Capacity check in accordance with product and HU
If you work with fixed storage bins or use the putaway strategy Addition to Existing Stock, we recommend a capacity check. In bulk storage, the capacity check is performed via the block definition.
Capacity Check in Accordance with Capacity Key Figure
You can also use a capacity key figure to control how a product is put away in a storage bin. Here the system calculates the capacity consumption in different ways, depending on the capacity check chosen:
· Capacity check in accordance with product
The system calculates the capacity consumption for the product on the basis of the quant (quantity of a product with the same attributes).
· Capacity check in accordance with HU
In the case of HU checks, the system calculates the capacity consumption on the basis of the HU.
· Capacity check in accordance with product and HU
In the case of mixed storage, we recommend the capacity check in accordance with the product and HU.
The capacity consumption of a product refers to the product quantity and is therefore specified as a variable in the system, and updated in the quant. The capacity consumption of an HU is specified as a constant capacity consumption, and is updated in the HU.
Quant and HU data is updated for each storage bin as remaining capacity.
You have to define the type of capacity check as well as the capacity consumption of the product and HU before the first putaway. Subsequent changes to these parameters result in automatic changes to storage bins, HUs, and quants.
