Getting StartedSU53 - Display Auth Data

SU53 – Display Auth Data

Troubleshooting security issues is one of the daily tasks of any security administrator. The first method of investigating authorization failures is the ubiquitous SU53 transaction. It involves us asking the affected user to run the step(s) to replicate the issue and immediately on getting the error, execute /nsu53 through the command window. The screen-shots below show the sequence of actions.

The user tries to create another user through SU01 and gets an authorization error

SU01- Create User
SU01- Create User

The user gets a pop with the message that he doesn’t have authorization to create user.

SU01 - Authorization Error
SU01 - Authorization Error

Many times clicking the help button can provide important information about the background of the error.

To get the SU53 screen, we execute /nsu53 from the command window immediately after getting the error. The SU53 window shows the last check for an authorization which has returned a non zero value (authorization failure) for the user.

The biggest limitation of SU53 is the fact that it only shows the last authorization failure of an user. In a typical transaction, there can be an entire sequence of authorization checks, any of which might fail. To view the entire sequence of authorization checks, we use the authorization trace tool (transaction ST01).

      HI BlackPro,

      Glad that you like the site. I am based in India. In case you have a general security question which might benefit others as well, feel free to ask. I will surely try to include it in a future post.

      However, for very specific issues I have found the SAP sdn security forum to be more effective than a personal site like this as a huge number of security experts access it daily.

      Best Regards,
      Aninda

    • Hi Pujitha,

      The SU53 transaction by design only shows the last authorization check failure for a user. If you suspect that there might be mutiple authorization failures for a single transaction, please use the security trace (tcode ST01) for the user under test. It will give you a list of authority checks faced by the user and can be used to troubleshoot complicated security scenarios.

      Aninda

      Most of the docs I have are SAP copyrighted ones so it would not be right for me to post these on a public forum. I have found the installation guides for GRC that you download from SAP marketplace to be very informative.

      In the first portion SU53 screenshot above, SAP system is checking for V_KNA1_VKO object with the values given. The next portion of su53 (below User’s Authorization Data LSUWESTJ) mentions the authorizations for the same object which is present with the user. The check fails as the exact values checked by the system are not present in the user master.

      There is button in the tool bar of Su53 transaction which allows you to switch users. Use it.

    how can we judge or confirm the screen shot(su53) send by end user is his last authorization failure.
    Date and time is the only way or is der another option

    • Hi Syed,

      The Su53 screenshot is designed by SAP to return the last authorization failure for a user. However, basing your analysis on Su53 can be misleading in a large number of cases. A ST01 trace is a much better bet in such cases.

    i include se11 in development role assign to one user which should have ACTIVIT 01,02 (create and change).but running su53 for that screen error showing that ACTIVIT 03 display should include in S_develope obj. how can i restrict 03 display for that development role ?
    where i need to change default value in s_develop.

    I need help please…………..

      SU53 is often misleading. Try a trace ST01. Also giving change/create in S_DEVELOP without display doesn’t make much sense.

    Could you plz tell me how to analyse a SU53 Screenshot?For example user tells that he has no Authorization to create users and he sent you the above screenshot,then what will you do?

    Hi Aninda,

    I have an issue with SU53 not recording the last authorization failure. I created a user with no authorizations, logged in with that user, executed a transaction and it says the user has no authorization to use that transaction. Then I logged in as a user that has authorization to execute SU53, switched users to the user that doesn’t have any authorizations and it didn’t show any authorization failures. Any idea what the problem may be? I’ve never seen SU53 not work.

    Reply
    • Aninda

      So SU53 doesn’t work at all in the system? In such a case you can investigate the profile parameters which control SU53. If its just for the one case you mentioned then I am not sure about the problem. But would you ever actually face this problem in a real scenario?

    Hi Aninda,

    Do you have any idea SU53 data stores in any table for temporally or permanently.
    or it will not have any table. i was wondering.

    Hi Aninda,

    In my view , su53 data are not stored in any table , instead its there in memory only.
    Let me know if you come across the table which stores su53 failed attempts .
