When using the hierarchical tree for storing assets in order to keep the tree as small as possible and more manageable sub locations can be defined at the lowest level rather than defining storage locations; the intention behind the hierarchical tree is to direct a member to a general area to locate an asset.

For example you may have a shelving system in a building that contains many boxed items but rather than add a storage item and therefore asset for every container box add a sub location of container box as typically the contents of the box will be written on the box anyway and the member just needs to know which shelving system to look at.

Sub locations therefore typically only contain one storage compartment and are assets where it is overkill to add an individual asset item for each one; NOTE: when you still need to record the value of these sub location assets you can still add one overall asset for the total quantity and assign the quantities to the assets they are located in for reporting purposes.

To add storage locations use menu option "Rescue Organization Manager -> General Lists" and select the "Asset sub location" list.
