• What is the cause and solution for SAP error message IDSAU328 - You cannot specify more than one certificate as the main certificate ?

  The SAP error message IDSAU328, which states "You cannot specify more than one certificate as the main certificate," typically occurs in the context of managing digital certificates within the SAP system. This error indicates that there is an attempt to designate multiple certificates as the "main" certificate, which is not allowed.
  Cause:
  
  Multiple Main Certificates: The primary cause of this error is that the system has been configured with more than one certificate marked as the main certificate. In SAP, only one certificate can be designated as the main certificate for a specific purpose (e.g., for secure communication).

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Certificates:
  
  Navigate to the transaction code where you manage certificates (e.g., STRUST).
  Review the list of certificates and identify which ones are marked as the main certificate.
  
  
  
  Remove or Change Main Certificate:
  
  If you find multiple certificates marked as main, you need to decide which one should remain as the main certificate.
  Change the status of the other certificates to non-main or remove the main designation from them.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save your changes and exit the transaction.
  
  
  
  Test the Configuration:
  
  After resolving the issue, test the configuration to ensure that the system is functioning correctly with the designated main certificate.
