• What is the cause and solution for SAP error message SAML2_CONFIG_UI018 - Select the certificate using the F4 help ?

  The SAP error message SAML2_CONFIG_UI018 typically occurs in the context of configuring SAML (Security Assertion Markup Language) in SAP systems, particularly when setting up Single Sign-On (SSO) configurations. This error indicates that the system expects you to select a certificate but none has been selected or available.
  Cause:
  The error arises when:
  
  You are trying to configure SAML settings, and the system requires a digital certificate for signing or encryption.
  The certificate selection field is empty, and the system prompts you to select a certificate using the F4 help (which is the standard SAP function for providing a list of possible values).
  
  Solution:
  To resolve the SAML2_CONFIG_UI018 error, follow these steps:
  
  
  Access the SAML2 Configuration:
  
  Go to transaction code SAML2 in your SAP system.
  
  
  
  Navigate to the Certificate Section:
  
  In the SAML2 configuration screen, look for the section where you need to select a certificate (usually under the "Identity Provider" or "Service Provider" settings).
  
  
  
  Select a Certificate:
  
  Click on the field where the certificate is to be selected and press the F4 key. This will open a list of available certificates.
  If there are no certificates listed, you may need to create or import a new certificate.
  
  
  
  Import or Create a Certificate:
  
  If you need to create a new certificate, you can do so using transaction code STRUST (for managing SSL certificates).
  In STRUST, you can create a new PSE (Personal Security Environment) or import an existing certificate. Make sure to save your changes.
  
  
  
  Return to SAML2 Configuration:
  
  After ensuring that a valid certificate is available, return to the SAML2 configuration screen and select the appropriate certificate using the F4 help.
  
  
  
  Save Your Configuration:
  
  Once you have selected the certificate, save your configuration.
