• What is the cause and solution for SAP error message SCV_API034 - Results node &1 has different types (&2 does not match &3) ?

  The SAP error message SCV_API034 indicates that there is a type mismatch in the results node of an API call. Specifically, it means that the expected data type for a particular field does not match the actual data type being provided. This can occur in various scenarios, such as when working with APIs, data services, or integration scenarios in SAP.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the data being sent or received does not match the expected data type defined in the API or service. For example, if the API expects a string but receives an integer, this error will occur.
  Incorrect Mapping: If you are using a mapping tool or middleware, the mapping between the source and target fields may be incorrect, leading to type mismatches.
  Changes in API Definition: If the API definition has changed (e.g., a field's data type was modified), and the consuming application has not been updated accordingly, this error can arise.
  Data Quality Issues: Sometimes, the data itself may contain unexpected values that do not conform to the expected data types.
  
  Solution:
  
  Check API Documentation: Review the API documentation to understand the expected data types for each field in the results node. Ensure that the data being sent matches these expectations.
  Validate Data Types: Before making the API call, validate the data types of the values being sent. Ensure that they conform to the expected types (e.g., string, integer, date).
  Update Mapping: If you are using a mapping tool, check the mappings to ensure that the source and target fields are correctly aligned in terms of data types.
  Error Handling: Implement error handling in your application to catch such errors and log them for further analysis. This can help in identifying the root cause more quickly.
  Test with Sample Data: Use sample data that conforms to the expected types to test the API call. This can help isolate whether the issue is with the data being sent or with the API itself.
  Consult with Developers: If you are unable to resolve the issue, consult with the developers or the team responsible for the API to get insights into any recent changes or known issues.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific API you are working with.
  API Versioning: Ensure that you are using the correct version of the API, as different versions may have different data type requirements.
  Debugging Tools: Utilize debugging tools available in SAP to trace the API calls and inspect the data being sent and received.
  
  By following these steps, you should be able to identify and resolve the SCV_API034 error effectively.
