• What is the cause and solution for SAP error message SUID01200 - Local user &1 cannot be changed by IDoc ?

  The SAP error message SUID01200 indicates that a local user (identified by &1) cannot be changed via an IDoc (Intermediate Document). This error typically arises when there is an attempt to modify user data through IDocs, but the system restricts such changes for local users.
  Cause:
  
  Local User Restrictions: The user in question is a local user, and SAP does not allow changes to local user data through IDocs for security and integrity reasons.
  IDoc Configuration: The IDoc type or message type being used may not be configured to handle changes to local users.
  Authorization Issues: The user or process attempting to make the change may not have the necessary authorizations to perform the operation.
  
  Solution:
  
  Direct Change: If you need to change the local user, do so directly in the SAP GUI using transaction SU01 (User Maintenance) instead of trying to do it through an IDoc.
  Check IDoc Configuration: Ensure that the IDoc type and message type you are using are appropriate for the changes you want to make. If you need to change user data via IDocs, consider using a different approach or configuration.
  Review Authorizations: Check the authorizations of the user or process that is attempting to make the change. Ensure that they have the necessary permissions to modify user data.
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or security team for best practices regarding user management and IDoc processing.
