• What is the cause and solution for SAP error message WFD_WP1_MSG023 - CanÆt authenticate Master Data Integration using OAuth 2.0. ?

  SAP Error Message:
  WFD_WP1_MSG023 Can't authenticate Master Data Integration using OAuth 2.0.
  
  Cause
  This error occurs when the SAP system (often SAP Workflow or SAP Cloud Platform Integration) tries to authenticate with the Master Data Integration (MDI) service using OAuth 2.0 but fails. The failure can be due to several reasons:
  
  Invalid or expired OAuth 2.0 token: The access token used for authentication is no longer valid or has expired.
  Incorrect OAuth 2.0 client credentials: The client ID, client secret, or token endpoint URL configured in the system is incorrect.
  Misconfiguration in OAuth 2.0 setup: The OAuth 2.0 flow (e.g., client credentials grant) is not properly configured in SAP or in the Identity Provider (IdP).
  Connectivity issues: Network problems preventing the SAP system from reaching the OAuth token service.
  Authorization issues: The OAuth client does not have the required permissions/scopes to access the MDI service.
  Clock skew: Significant time difference between SAP system and OAuth server causing token validation
