• What is the cause and solution for SAP error message IUUC_CDC_API004 - RFC Destination &1: Not authorized to subscribe ?

  The SAP error message IUUC_CDC_API004 indicates that there is an issue with authorization when trying to subscribe to a Change Data Capture (CDC) service via a Remote Function Call (RFC) destination. This error typically arises in scenarios where the system is trying to establish a connection to a source system for data replication or change tracking, but the user or service account does not have the necessary permissions.
  Cause:
  
  Insufficient Authorizations: The user or service account that is being used to connect to the RFC destination does not have the required authorizations to perform the subscription operation.
  Incorrect RFC Destination Configuration: The RFC destination may not be correctly configured, leading to authorization issues.
  User Role Issues: The user may not have the appropriate roles assigned that include the necessary authorizations for CDC operations.
  
  Solution:
  
  
  Check User Authorizations:
  
  Ensure that the user or service account has the necessary authorizations to perform CDC operations. This typically includes roles related to data replication and change data capture.
  You can use transaction SU53 to analyze the authorization check failure after the error occurs. This will show you which authorization objects are missing.
  
  
  
  Review RFC Destination Settings:
  
  Go to transaction SM59 and check the configuration of the RFC destination that is being used. Ensure that it is set up correctly and points to the right target system.
  Test the RFC connection to ensure it is working properly.
  
  
  
  Assign Required Roles:
  
  If the user lacks the necessary roles, you may need to assign roles that include the required authorizations for CDC. Common roles might include those related to data replication, such as SAP_BC_CDC_* roles or similar.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for Change Data Capture and the specific authorizations required for the operations you are trying to perform.
