• What is the cause and solution for SAP error message /IWFND/CM_MGW_RT112 - Property name: '&1' ABAP field name '&2' already exists ?

  The SAP error message /IWFND/CM_MGW_RT112 indicates that there is a conflict in the naming of properties in your OData service. Specifically, it means that a property name (represented by &1) is already being used for another ABAP field (represented by &2) in the context of the OData model.
  Cause:
  This error typically occurs when:
  
  You have defined multiple properties in your OData service that share the same name.
  There is a naming conflict between the properties defined in the OData model and the underlying ABAP data structure (e.g., a structure or table).
  The OData service is trying to expose fields that have the same name, leading to ambiguity.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Property Names: Review the properties defined in your OData service. Ensure that each property has a unique name. If you find duplicates, rename them to ensure uniqueness.
  
  
  Review ABAP Data Structure: Check the underlying ABAP structure or table that the OData service is based on. Make sure that the field names do not conflict with the property names defined in the OData service.
  
  
  Adjust the OData Model: If necessary, adjust the OData model to ensure that the property names are distinct from the ABAP field names. You can do this by modifying the metadata of the OData service.
  
  
  Regenerate the OData Service: After making changes, regenerate the OData service to ensure that the changes are reflected in the service definition.
  
  
  Test the Service: Once you have made the necessary adjustments, test the OData service to ensure that the error no longer occurs.
  
  
  Related Information:
  
  OData Service Metadata: You can view the metadata of your OData service using the /IWFND/MAINT_SERVICE transaction in SAP. This will help you identify the properties and their corresponding ABAP fields.
  ABAP Dictionary: Use transaction SE11 to check the structure or table definitions in the ABAP Dictionary to identify any naming conflicts.
  SAP Notes: Check for any relevant SAP Notes that might address similar issues or provide additional guidance on OData service configuration.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly without naming conflicts.
