  Invalid or incomplete parameters passed during the client creation process.
  Backend system or service issues, such as missing required services or components.
  Certificate or trust issues if the OAuth client creation involves SSL/TLS communication.
  
  
  Solution
  To resolve the WGDS_PROCESS775 error, follow these steps:
  
  
  Check OAuth 2.0 Client Configuration:
  
  Go to transaction OA2C_CONFIG or the relevant OAuth 2.0 client configuration UI.
  Verify that all mandatory fields (client ID, client secret, redirect URIs, scopes, etc.) are correctly maintained.
  Ensure no duplicate client IDs or names exist.
  
  
  
  Verify Authorizations:
  
  Ensure the user or service account creating the OAuth client has the necessary SAP authorizations.
  Check roles related to OAuth 2.0 client management, e.g., SAP_OAUTH_ADMIN or similar.
  
  
  
  Check Connectivity:
  
  Test connectivity to the OAuth 2.0 provider or IdP.
  Use transaction SMICM or network tools to verify no firewall or network issues block communication.
  
  
  
  Review Logs and Traces:
  
  Check system logs (transaction SM21) and application logs (transaction SLG1) for detailed error messages.
  Enable trace for OAuth 2.0 client creation if available.
  
  
  
  Check for Duplicate Clients:
  
  Search existing OAuth clients to ensure the client ID or name you want to create is not already in use.
  
  
  
  Validate Certificates and Trust:
  
  If SSL/TLS is involved, ensure the SAP system trusts the IdP’s certificate.
  Use transaction STRUST to manage certificates.
