• What is the cause and solution for SAP error message 01647 - You are not authorized to change SNC data of users ?

  The SAP error message "01647 You are not authorized to change SNC data of users" typically occurs when a user attempts to modify Secure Network Communications (SNC) settings for users in the SAP system but lacks the necessary authorizations to do so.
  Cause:
  The error is caused by insufficient authorizations in the user's profile. Specifically, the user does not have the required permissions to change SNC-related data for other users. This is often related to the following:
  
  Missing Authorization Objects: The user may not have the necessary authorization objects assigned to their role, particularly those related to SNC settings.
  Role Configuration: The roles assigned to the user may not include the necessary permissions to modify SNC data.
  User Type: The user may be trying to change SNC data for a user type that requires higher privileges (e.g., system users or service accounts).
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to see which authorization check failed. This will provide insight into what specific authorization is missing.
  
  
  
  Review Role Assignments:
  
  Check the roles assigned to the user in transaction SU01 (User Maintenance) or PFCG (Role Maintenance).
  Ensure that the roles include the necessary authorization objects for SNC data changes, such as S_USER_AUTH or S_USER_PRO with the appropriate activity codes.
  
  
  
  Modify Roles:
  
  If the necessary authorizations are missing, you may need to modify the existing roles or create a new role that includes the required authorizations.
  Ensure that the role is properly assigned to the user.
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary access to modify roles or authorizations, consult with your SAP security team or administrator to request the required permissions.
  
  
  
  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.

  Documentation: Refer to SAP documentation for detailed information on SNC configuration and user authorizations.
