Transaction: WE20
This task is used to demonstrate how to create the Partner for the Logical System you created earlier. Note that the LS Partner Type is used for all ALE distribution scenarios.
In the SAP R/3 System home window, type WE20 into the command field and then click Continue (Enter) to display the Partner Profile: Initial Screen window.

Type the name of the logical system created previously into the Partner number field, select LS for the Partner type, and select Create. This creates the Partner, and displays the Create Partner Profile <Partner Number> window.

Under the Classification tab, select ALE for the Partner class and A (Active) for the Partner status, then Save. You now have created the Partner, and need to continue to the next section to configure the Partner Profile.
