• What is the cause and solution for SAP error message RSEC013 - User names with '.' (period) cannot be processed ?

  The SAP error message RSEC013 indicates that user names containing a period (.) cannot be processed. This error typically arises in the context of user management and authorization in SAP systems, particularly when dealing with user IDs that include special characters.
  Cause:
  The primary cause of this error is that SAP does not allow periods in user names due to restrictions in its user management and authorization framework. User names are often used in various security and authorization checks, and the presence of a period can lead to complications in processing these checks.
  Solution:
  To resolve the RSEC013 error, you can take the following steps:
  
  
  Change User Name: If possible, change the user name to remove the period. This can be done through the user management transaction (e.g., SU01) by editing the user profile and updating the user ID to a valid format that does not include a period.
  
  
  Create a New User: If changing the existing user name is not feasible (for example, if the user has existing authorizations or roles assigned), consider creating a new user with a valid name and transferring the necessary authorizations and roles from the old user to the new one.
  
  
  Check User Creation Processes: If user names are being generated automatically (e.g., through an interface or a script), ensure that the logic for generating user names does not include periods or other invalid characters.
  
  
  Review Documentation: Consult SAP documentation or support notes for any updates or specific guidelines regarding user name conventions in your version of SAP.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional context or solutions for this error. You can search the SAP Support Portal for notes related to user management and authorization issues.
  User Management Transactions: Familiarize yourself with user management transactions such as SU01 (User Maintenance), SU10 (Mass User Maintenance), and SUIM (User Information System) for managing user accounts and authorizations effectively.
  Authorization Checks: Understand how user names are used in authorization checks and the implications of changing user names on existing roles and profiles.
  
  By following these steps, you should be able to resolve the RSEC013 error and ensure that user names conform to SAP's requirements.
