Supply Network
A supply network consists of transportation lanes. It determines which products can be delivered between which locations.
You can only procure products when transportation lanes exist between the possible locations in your system. You import the transportation lanes through the interface.
In SAP F&R, the supply network is made up of the following levels:
Transportation Lane for Subranges
Defines replenishment-relevant settings at the subrange level or for all subranges. The transportation lane exists between a source location and (one or all) target locations, as well as (one or all) subranges. When distribution centers are involved, the subranges are merchandise categories; when external vendors are involved, they are vendor subranges.
Transportation Lane for Products
Exists between a source location and (one or all) target locations.
If you have defined certain parameters for the transportation lanes for products and subranges as modifiable and time-dependent in Customizing, you can change these parameters in mass processing. To maintain the transportation lanes of a supply network, go to the

Source determination
SAP F&R uses the transportation lanes for source determination. The system uses parameter BWSCL
of the location product to evaluate a supply source control, which determines the available source locations from all transportation lanes. Of these locations, source determination selects a valid internal or external supply source – by priority, if defined.
Depending on your settings in client-specific master data Customizing, you may also be able to use the following functions in source determination:
If SAP F&R determines more than one valid transportation lane, it selects the lane with the highest priority. You can use the purchasing organization for source determination. In this case, SAP F&R gives higher priority to transportation lanes whose purchasing organization is identical to the main purchasing organization of the target site (compared to transportation lanes without an identical purchasing organization). For more information, see Inbound Interfaces for Purchasing Organization Data.
You can decide whether the system should only consider transportation lanes with listed products in source locations. In this case, a listing check is also performed for the distribution center (DC) determined as the supply source. If the selected product is not listed at the DC, SAP F&R rejects the DC as a source of supply.
