One
may notice in SAP NetWeaver
based systems that user SAPJSF is
logged in the system. It can be seem in t-codes like SM66, SM04 etc. Such a
user ID is basically technical user (type of system or communication) that
serves a purpose of communication between UME (User Management Engine of AS
Java) and ABAP user management. Means it communicates between two stacks of NetWeaver: ABAP and
JAVA in landscapes where both stacks are present (dual stack systems). In the
landscapes where only Java stack systems are present it is used for internal
communication.
In
the ABAP stack it exits in clients 000 and 001.
The
user is created during the systems installation. JSF stands for Java Security
Framework.
For
BW people the user can be familiar because it is also used to run BW (BEx)
queries from SAP NetWeaver
Portal (former name SAP Enterprise Portal). While the query is running from
the Portal the user can be observed in the ABAP stack as logged user.
