• What is the cause and solution for SAP error message /IWPGW/TGW_TCM_MSG006 - Mapped field '&1' for property '&2' missing in target structure ?

  The SAP error message /IWPGW/TGW_TCM_MSG006 indicates that there is a mapping issue in the Gateway service where a field that is expected in the target structure is missing. This typically occurs in the context of OData services when the mapping between the source and target structures is not correctly defined or when the target structure does not contain the expected fields.
  Cause:
  
  Missing Field in Target Structure: The field specified in the error message (&1) is not present in the target structure defined for the OData service.
  Incorrect Mapping: The mapping configuration between the source and target structures may not be set up correctly, leading to discrepancies.
  Changes in Data Model: If there have been recent changes to the data model (e.g., adding or removing fields), the OData service may not have been updated accordingly.
  Service Definition Issues: The service definition might not include the necessary fields, or the service might not be activated properly.
  
  Solution:
  
  Check Target Structure: Verify that the target structure defined in the OData service includes the field mentioned in the error message. If it is missing, you may need to add it.
  Update Mapping: Review the mapping configuration in the service definition. Ensure that all fields from the source structure are correctly mapped to the target structure.
  Regenerate Service: If changes have been made to the underlying data model, regenerate the OData service to reflect those changes. This can often be done through transaction /IWFND/MAINT_SERVICE.
  Activate Service: Ensure that the OData service is activated and that all necessary components are properly configured.
  Check for Transport Issues: If the issue arises after a transport, ensure that all relevant objects were transported correctly and that there are no missing components.
