Basic Authentication (SAP Library - Internet Communication Framework)

Basic Authentication

If Basic Authentication is used to log on to SAP Web Application Server (in other words, if no Anonymous Logon Data is set and the standard logon procedure is used, see Logging On to SAP Web Application Server), either the standard SAP user or an Internet user can be used.

The default SAP user is the user name that is entered in Transaction SU01.
The Internet user is the alias name that can be longer than the normal SAP user name. This is also set in SU01.

Depending on the settings, the input in the Basic Authentication popup is interpreted as either a user name or an alias.
