  • What is the cause and solution for SAP error message TN845 - No authorization to modify the SAP kernel checks ?

    The SAP error message TN845 indicates that a user does not have the necessary authorization to modify the SAP kernel checks. This typically occurs when a user attempts to perform actions that require elevated permissions, such as modifying system settings or configurations related to the SAP kernel.

    Cause:

    1. Insufficient Authorizations: The user does not have the required authorizations assigned in their user profile to perform the action.
    2. Role Configuration: The roles assigned to the user may not include the necessary permissions for kernel modifications.
    3. System Configuration: The system may be configured to restrict certain actions to specific user groups or roles.

    Solution:

    1. Check User Authorizations:

      • Use transaction code SU53 immediately after encountering the error to analyze the authorization check. This will show which authorization objects were checked and which ones failed.
      • Review the user’s roles and authorizations in transaction SU01 (User Maintenance) or PFCG (Role Maintenance).
    2. Modify User Roles:

      • If the user lacks the necessary authorizations, you may need to assign additional roles that include the required permissions. This typically involves adding roles that contain the necessary authorization objects related to kernel modifications.
      • Consult with your SAP security team or administrator to ensure that the user is granted the appropriate roles.
    3. Authorization Object:

      • The specific authorization object that may be relevant for kernel modifications is S_USER_AUTH or S_TCODE (for transaction codes). Ensure that the user has the necessary permissions for these objects.
    4. Consult Documentation:

      • Review SAP documentation or notes related to the specific transaction or action being performed to understand the required authorizations.
    5. Testing:

      • After making changes to the user’s roles or authorizations, have the user log out and log back in to test if the issue is resolved.

    Related Information:

    • SAP Notes: Check SAP Notes for any specific guidance or updates related to the TN845 error message.
