Inventory Availability

As a new sales order is processed, unless it is placed on hold or is outside the inventory reservation window, availability checking will be performed.  If the sales office location does not have enough inventory they have two choices:  they can wait for inventory to be replenished or they can source the order from a remote site (another location or an outside vendor).  Furthermore, if the sales office location only has a partial amount of the requested inventory, they can choose to source part of the order from their stock location and outsource the balance.

Note that the key to this processing is Reference File category 412 - Order Processing System Defaults.  On this category, the Overreservation flag needs to be set to N (no) otherwise all lines will be reserved even if inventory is currently not available and there will be no trigger record to attempt remote sourcing.
