  The SAP error message ECATT391, which states "Selected files do not match WEBSERVICE interface &1," typically occurs in the context of using the eCATT (extended Computer Aided Test Tool) for automated testing of web services. This error indicates that the files you are trying to use do not conform to the expected structure or format defined by the web service interface.
  Cause:
  
  Mismatch in File Structure: The files you are trying to upload or use may not have the correct structure or format that the web service expects. This could be due to missing fields, incorrect data types, or additional fields that are not defined in the web service interface.
  Incorrect Mapping: The mapping between the file content and the web service parameters may not be correctly defined, leading to a mismatch.
  Versioning Issues: If the web service interface has been updated or changed, the files may still be in an older format that is no longer compatible.

  Solution:
  
  Check File Structure: Review the structure of the files you are using. Ensure that they match the expected input format defined by the web service interface. This includes checking for required fields, data types, and any specific formatting requirements.
  Update Mapping: If you are using a mapping tool or configuration, ensure that it correctly maps the fields in your files to the parameters expected by the web service.
  Verify Web Service Interface: Check the web service documentation to confirm the expected input format and ensure that your files comply with it. If there have been recent changes to the web service, update your files accordingly.
  Test with Sample Data: Use sample data that is known to work with the web service to verify that the issue is with your files and not with the web service itself.
  Encoding Check: Ensure that the files are saved in the correct encoding format (e.g., UTF-8) that the web service can process.
