Whats the functional difference between CUA and UME?

Hi All,

A small query regarding UME (User Management Engine) and CUA ( Central User Administration). Whats the functional difference between these two. I read in help documents that UME will be used for SAP WebAS Java server. But I read that it can be used for ABAP engine as well. Then why do we need to use CUA when we have user friendly interface tool like UME. According to my knowledge from help documentation, UME comes pre installed. so we dont need to install it as we have to do for CUA.

Can any help me in understanding the difference between these two. Thanks in advance. Good day.

Regards,

Farooq.

    Hi,

    Indeed good question.

    It depends on installation type you selected. But are responsible for user administration in terms of creating, deleting, updating and role assignment tasks to users and groups.

    --CUA is meant for ABAP Installation. CUA is responsible for entire landscape user administration works with RFC connection talking to all ABAP systems

    --UME is meant for Java installations, plus UME is responsible for handling communication between ABAP users and java users.

    UME

    For more details see below links all advantages and disadvantages of both systems and comparisons deliberately.

    Hi,

    There are differences b/w the two based in the type of installation being carried out. As an example, if you are performing an ABAP+JAVA install then you are given the option of managing your users via the CUA or UME (CUA prefered in this case).

    If you opt to install only the Java portion (stand-alone) of a NW installation then your only user management option is the UME (as an example the JDI in most case may not be a ABAP+JAVA installation).

    Also there are pitfalls in using the UME for a ABAP+JAVA installation depenfing on the SP you are on. An example of this would be the limitions of using the passwd reset option using the browser. Older J2EE SP's dont support this option very well thus they will recommend you upgrade.

    Pro's and Cons are all discussed on the SAP website under netweaver section.

    Hope this helps.
