After you activate QAD Warehousing in Warehouse Management Control (4.24), you do not have to link all locations to a warehouse. If a site is defined without any warehouse, the picking process is a standard system picking process. The algorithms will not be started.

If you define at least one warehouse in a site, active or not, all locations of that site have to be linked to a warehouse. Warehouse picking algorithms are started instead of standard picking rules.

This is useful if you have multiple sites but do not use warehouse functions at all of them. Generally, you do not want to make additional warehouse setup such as defining warehouses, linking locations to warehouses, and defining picking algorithms, unless these features are needed.
