  The SAP error message /UI2/CDM3_EXP003 &1 entity &2 not exposed typically indicates that a specific entity (data model) is not exposed for use in the SAP Fiori application or the OData service. This can occur in scenarios where the entity is not properly configured or is not included in the relevant data model.
  Cause:
  
  Entity Not Exposed: The entity you are trying to access is not exposed in the OData service or the Fiori application.
  Missing Configuration: The entity might not be included in the service definition or the relevant CDS (Core Data Services) view.
  Authorization Issues: There may be authorization restrictions preventing access to the entity.
  Transport Issues: If the system is newly set up or has recently undergone a transport, the entity might not have been properly activated or transported.
  
  Solution:
  
  
  Check OData Service:
  
  Go to the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE).
  Ensure that the OData service is active and that the entity is included in the service definition.
  
  
  
  Check CDS View:

  Adjust Authorization:
  
  Verify that the user has the necessary authorizations to access the entity. Check the roles assigned to the user and ensure they include access to the relevant OData service.
  
  
  
  Re-activate the Service:
  
  Sometimes, simply reactivating the OData service or the CDS view can resolve the issue. You can do this in the Service Builder or the ABAP Development Tools.

  If the issue arose after a transport, ensure that all necessary objects were included in the transport request and that they have been properly imported into the target system.
  
  
  
  Debugging:
