• What is the cause and solution for SAP error message 01648 - You are not authorized to change SNC data of users in group & ?

  The SAP error message "01648 You are not authorized to change SNC data of users in group &" typically indicates that the user attempting to make changes to the Secure Network Communications (SNC) data for users in a specific user group does not have the necessary authorizations.
  Cause:
  
  Authorization Issues: The user lacks the required authorizations to modify SNC data for the specified user group.
  User Group Restrictions: The user may not be part of the user group or may not have the necessary roles assigned to manage SNC settings for that group.
  Configuration Settings: There may be specific configuration settings in the SAP system that restrict access to SNC data.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check the authorization check that failed. This will provide insight into which specific authorization is missing.
  Review the user's roles and profiles in transaction SU01 or PFCG to ensure they have the necessary authorizations to change SNC data.
  
  
  
  Assign Necessary Roles:
  
  If the user does not have the required roles, you may need to assign them roles that include the necessary authorizations for SNC data management. Common roles that might include these authorizations are those related to user administration or security.
  
  
  
  Consult with Security Administrator:
  
  If you are not authorized to make changes to user roles, consult with your SAP security administrator or basis team. They can help identify the necessary roles and make the required changes.
  
  
  
  Review Group Settings:
  
  Ensure that the user is part of the user group they are trying to modify. If not, they may need to be added to that group or given permissions to manage users in that group.
  
  
  
  Check SNC Configuration:
  
  Review the SNC configuration settings in the SAP system to ensure that there are no additional restrictions in place that could be causing this issue.
