  The SAP error message SADL_GW_EXP_VOCAN007 indicates that the system is unable to determine the data type for a specific field or entity in the context of the SAP Gateway and the Service Data Layer (SADL). This error typically arises when there is a mismatch or an issue with the metadata definitions in the OData service or when the underlying data model is not properly defined.
  Causes:
  
  Missing or Incorrect Metadata: The metadata for the OData service may not be correctly defined, leading to the inability to determine the data type.
  Inconsistent Data Model: There may be inconsistencies in the data model, such as missing associations or incorrect data type definitions in the underlying database or data source.
  Changes in Data Model: If there have been recent changes to the data model (e.g., adding or modifying fields) without updating the OData service, this can lead to errors.
  Service Registration Issues: The OData service may not be properly registered or activated in the SAP Gateway.
  
  Solutions:
  
  
  Check Metadata Definitions: Review the metadata definitions for the OData service to ensure that all fields and data types are correctly defined. You can do this by accessing the service in the SAP Gateway Service Builder (transaction code SEGW).
