  The SAP error message /IWFND/CM_MGW_RT120 Data type not found '&1' typically occurs in the context of SAP Gateway and OData services. This error indicates that the system is unable to find a specified data type that is referenced in the OData service or the underlying data model.
  Causes:
  
  Missing Data Type Definition: The data type that is being referenced in the OData service is not defined in the system.
  Incorrect Mapping: There may be an issue with the mapping of the data type in the service definition or the data model.
  Transport Issues: If the OData service or its associated data types were transported from another system, there may have been issues during the transport process.
  Activation Issues: The service or the data model may not be activated properly, leading to missing references.
  Namespace Issues: The data type might be defined in a different namespace that is not being recognized.
  
  Solutions:
  
  
  Check Data Type Definition:
  
  Go to the Data Dictionary (SE11) and check if the data type exists. If it does not, you may need to create it or correct the reference in the OData service.
  
  
  
  Review OData Service:

  Debugging:
