• What is the cause and solution for SAP error message CMS186 - No Certificate with Fingerprint &1 Known ?

  The SAP error message CMS186 "No Certificate with Fingerprint &1 Known" typically occurs in the context of SAP's Cryptographic Management System (CMS) when the system is unable to find a certificate that matches the specified fingerprint. This can happen in various scenarios, such as when trying to establish secure connections or when performing cryptographic operations.
  Cause:
  
  Missing Certificate: The certificate with the specified fingerprint is not present in the system's certificate store.
  Incorrect Fingerprint: The fingerprint provided may be incorrect or may not match any of the certificates in the store.
  Expired Certificate: The certificate may exist but could be expired or invalid.
  Configuration Issues: There may be issues with the configuration of the cryptographic settings in the SAP system.
  
  Solution:
  
  
  Check Certificate Store: Verify that the certificate with the specified fingerprint is indeed present in the SAP system's certificate store. You can do this using transaction code STRUST.
  
  Navigate to STRUST and check the relevant certificate list.
  If the certificate is missing, you may need to import it.
  
  
  
  Import the Certificate: If the certificate is not found, you can import it into the system.

  Verify Fingerprint: Ensure that the fingerprint you are using is correct. You can check the fingerprint of the existing certificates in STRUST.
  
  
  Check for Expiration: If the certificate exists but is expired, you will need to renew or replace it with a valid certificate.
