  The SAP error message RTGP_APP004 indicates that a user is not authorized to use a specific change number in the system. This typically occurs in the context of change management processes, such as when working with change numbers in the SAP Engineering Change Management (ECM) module or similar functionalities.
  Cause:
  
  Authorization Issues: The user does not have the necessary authorizations to access or use the specified change number. This could be due to missing roles or permissions in the user's profile.
  Change Number Status: The change number may be in a status that does not allow it to be used (e.g., it might be locked or not released).
  Configuration Settings: There may be specific configuration settings in the system that restrict access to certain change numbers based on user roles or organizational units.
  
  Solution:
  
  
  Check User Authorizations:
  
  Review the user's roles and authorizations in the SAP system. Ensure that the user has the necessary permissions to access and use change numbers.
  Use transaction code SU53 immediately after encountering the error to see which authorization check failed. This can provide insights into what specific authorization is missing.

  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 access.
  
  
  
  Review Configuration:
  
  If the issue persists, review the configuration settings related to change management in your SAP system. This may involve checking the settings in transaction codes like SPRO (SAP Reference IMG) to ensure that there are no restrictions based on organizational units or other criteria.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CC01, CC02, CC03, and SU53 for managing change numbers and checking authorizations.
