Internal routings (IRs) are pathways through your warehouse that you want your inventory to take; however, it is the IR assignment that tells the system when to use the internal routing.

Once the routings are defined the next step is to determine when the specific flows are triggered.

Use Internal Routing Assignment Maintenance to associate a transaction type to a site and warehouse. When the system creates the transaction type, the material flow is initiated.

You can also define other optional parameters (item number, warehouse item type, address) to create more specific triggers.

There are three frames and nine fields in Internal Routing Assignment Maintenance used for configuration.
