• What is the cause and solution for SAP error message /IWFND/CM_MGW_RT160 - Structure type '&1' provided by the application does not exist ?

  The SAP error message /IWFND/CM_MGW_RT160 indicates that a structure type specified in an OData service does not exist in the system. This error typically occurs when the OData service is trying to access a data structure that has not been defined or has been incorrectly referenced.
  Cause:
  
  Missing Structure Definition: The structure type referenced in the OData service is not defined in the ABAP Dictionary.
  Typographical Error: There may be a typo in the name of the structure type in the OData service definition.
  Transport Issues: The structure may exist in the development environment but has not been transported to the quality or production environment.
  Incorrect Service Registration: The OData service may not be correctly registered or activated in the SAP Gateway.
  Changes in Data Model: If the underlying data model has changed (e.g., structures were deleted or renamed), the OData service may still reference the old structure.
  
  Solution:
  
  
  Check Structure Definition:
  
  Go to transaction SE11 (Data Dictionary) and check if the structure type exists. If it does not exist, you may need to create it or correct the reference in the OData service.
  
  
  
  Verify OData Service:
  
  Use transaction /IWFND/MAINT_SERVICE to check the OData service registration. Ensure that the service is active and correctly configured.
  Check the service implementation in transaction SEGW (Gateway Service Builder) to ensure that the structure is correctly referenced.
  
  
  
  Correct Typographical Errors:
  
  Review the code in the OData service implementation to ensure that the structure name is spelled correctly.
  
  
  
  Transport Issues:
  
  If the structure exists in the development environment but not in production or quality, ensure that the transport requests containing the structure definition have been released and imported into the target system.
  
  
  
  Rebuild OData Service:
  
  If changes were made to the underlying data model, you may need to regenerate the OData service. In transaction SEGW, you can right-click on the service and select "Generate Runtime Objects".
  
  
  
  Check for Dependencies:
  
  Ensure that all dependencies of the structure are also available in the system. Sometimes, a structure may depend on other types or tables.
