• What is the cause and solution for SAP error message /IWBEP/SBOD178 - Invalid Boolean. Please use ' ', 'X', 'TRUE', 'FALSE', '0' or '1' ?

  The SAP error message /IWBEP/SBOD178 Invalid Boolean. Please use ' ', 'X', 'TRUE', 'FALSE', '0' or '1' typically occurs in the context of SAP Gateway or OData services when a Boolean value is expected but an invalid value is provided. This error indicates that the system is unable to interpret the value as a valid Boolean.
  Cause:
  
  
  Invalid Input Value: The value provided for a Boolean field is not one of the accepted formats. The valid formats are:
  
  Empty string (' ')
  'X' (which is interpreted as true)
  'TRUE' (case-insensitive)
  'FALSE' (case-insensitive)
  '0' (interpreted as false)
  '1' (interpreted as true)
  
  
  
  Data Mapping Issues: If the data is being mapped from another source (like a database or an external API), the mapping might not be correctly converting the values to the expected Boolean format.
  
  
  Frontend Input Error: If the input is coming from a user interface, the user might have entered an invalid value.
  
  
  Solution:
  
  
  Check Input Values: Ensure that the values being sent to the OData service are one of the valid Boolean representations mentioned above. If you are constructing the request manually, double-check the values.
  
  
  Data Validation: Implement validation logic in your application to ensure that only valid Boolean values are sent to the backend. This can help prevent invalid data from being submitted.
  
  
  Debugging: If you are unsure where the invalid value is coming from, use debugging tools to trace the data flow and identify where the incorrect value is being introduced.
  
  
  Review Mapping Logic: If the data is being transformed or mapped from another source, review the mapping logic to ensure that it correctly converts values to the expected Boolean format.
  
  
  User Interface Improvements: If the input is from a user interface, consider adding dropdowns or radio buttons for Boolean fields to limit user input to valid options.
