• What is the cause and solution for SAP error message CRD_MDA120 - Error: Portal user &1 and system user &2 do not match ?

  The SAP error message CRD_MDA120 indicates a mismatch between the portal user and the system user. This typically occurs in scenarios where there is an integration between SAP systems and a portal, such as SAP NetWeaver Portal or SAP Fiori Launchpad. The error suggests that the user trying to access a resource in the portal does not match the expected user in the backend system.
  Cause:
  
  User Mismatch: The user logged into the portal does not correspond to the user in the backend system (e.g., SAP ERP, SAP S/4HANA).
  User Mapping Issues: There may be issues with the user mapping configuration between the portal and the backend system.
  Single Sign-On (SSO) Configuration: If SSO is configured, there might be a problem with the SSO setup that is causing the user credentials to not be passed correctly.
  User Roles and Authorizations: The user may not have the necessary roles or authorizations in the backend system to access the requested resource.
  
  Solution:
  
  Check User Credentials: Ensure that the user logged into the portal is the same as the user in the backend system. If they are different, log in with the correct user.
  User Mapping Configuration: Review the user mapping settings in the portal and ensure that they are correctly configured to match the backend system users.
  SSO Configuration: If using SSO, verify that the SSO configuration is correct and that the necessary certificates and settings are in place.
  Authorization Check: Ensure that the user has the required roles and authorizations in the backend system to access the resources they are trying to reach.
