How to fix this error?

1. In case of basic authentication over HTTPS make sure the issuer
certificate chain including intermediate certificates if any are
available in the certificate list of the <DS:TRAN.STRUST>STRUST</> PSE
being used.
2. In case of certificate based mutual authentication make sure the
following requirements are satisfied.
Make sure the issuer certificate chain including intermediate
certificates if any are available in the certificate list of the STRUST
PSE configured in the <DS:TRAN.SOAMANAGER>SOAMANAGER</> for the Consumer
proxy <ZH>CO_CODERINT_CONNECTIVITY_CHECK</>
The client certificate is issued by a signing authority which the server
trusts. For example in case of HCI the issuer of the client certificate
in STRUST PSE must be in the trust list of BIG-IP which acts as a
reverse proxy in front of the HCI tenant.
In the Consumer proxy authentication settings X.509 SSL Client
certificate is selected and the required PSE from STRUST is selected.

• What is the cause and solution for SAP error message COD_ERP_COMMON012 - SSL handshake with Middleware system did not succeed. ?

  The SAP error message "COD_ERP_COMMON012 SSL handshake with Middleware system did not succeed" typically indicates an issue with the SSL (Secure Sockets Layer) handshake process between the SAP system and a middleware system. This error can arise due to various reasons, including configuration issues, certificate problems, or network-related issues.
  Causes:
  
  Certificate Issues: The SSL certificate used by either the SAP system or the middleware may be expired, not trusted, or incorrectly configured.
  Cipher Suite Mismatch: The SSL/TLS protocols or cipher suites supported by the SAP system and the middleware may not match.
  Network Issues: Firewalls or network configurations may be blocking the SSL connection.
  Configuration Errors: Incorrect settings in the SAP system or middleware regarding SSL configuration.
  Java Key Store Issues: The Java Key Store (JKS) may not contain the necessary certificates or may be incorrectly configured.
  
  Solutions:
  
  
  Check SSL Certificates:
  
  Verify that the SSL certificates on both the SAP system and the middleware are valid and not expired.
  Ensure that the certificates are trusted by both systems. You may need to import the necessary certificates into the trust store of the SAP system.
  
  
  
  Review SSL Configuration:
  
  Check the SSL configuration settings in both the SAP system and the middleware. Ensure that they are set up to use compatible SSL/TLS versions and cipher suites.
  In the SAP system, you can check the SSL settings in transaction STRUST (for SSL certificates) and STRUSTSSO2 (for SSO configurations).
  
  
  
  Update Cipher Suites:
  
  If there is a mismatch in supported cipher suites, you may need to update the configuration to ensure both systems support the same cipher suites.
  
  
  
  Network Configuration:
  
  Ensure that there are no firewalls or network devices blocking the SSL connection between the SAP system and the middleware.
  Check for any proxy settings that may affect the connection.
  
  
  
  Java Key Store (JKS) Configuration:
  
  If using a Java-based SAP system, ensure that the Java Key Store contains the necessary certificates and is correctly configured.
  You can use tools like keytool to manage the JKS and verify its contents.
  
  
  
  Logs and Traces:
  
  Check the SAP system logs (transaction SM21) and the middleware logs for any additional error messages that may provide more context on the issue.
  Enable SSL debugging in the Java application server to get more detailed logs about the SSL handshake process.
  
  
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may address specific issues related to SSL configuration and troubleshooting.
  Documentation: Refer to the official SAP documentation for configuring SSL in your specific SAP environment.
  Community Forums: Engage with SAP community forums or support channels for additional insights and solutions from other users who may have faced similar issues.
  
  By systematically checking these areas, you should be able to identify and resolve the SSL handshake issue between your SAP system and the middleware.
