User accounts have to be configured with the type of user authentication that takes place when the Consumer system calls the web services on the Provider system. The following three options are offered.
Business User: The user logged on to the SAP Gateway also logs on the SAP system using their own user and credentials.
Anonymous user: The SAP system is called with an anonymous user.
Service User: The SAP system is called with a predefined service user.
For setting up the communication from the Consumer systems to the Provider systems, only the Business User option is required.
Proceed as follows to configure User accounts:
Log on to the SAP system where the SAP Gateway is installed.
Open transaction SOAMANAGER.
To create a new user account, choose New.
Enter a name for the user account.
In the next step, select Business User.
Activate the account.
Go to the Account Assignment tab.
Click New to create a new interface assignment.
In the Business Application field, press F4 and select the Provider system you created in the Creating a System Connection to Provider System.
Select Assign to all services within this business application.
From the Account drop-down list, select the account you have just created.
