• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE012 - Invalid double '&1' ?

  The SAP error message CDS_UNIT_MESSAGE012 Invalid double '&1' typically occurs in the context of Core Data Services (CDS) views or when working with data types in SAP systems. This error indicates that there is an issue with a double value that is being processed, where the value does not conform to the expected format or range.
  Cause:
  
  Invalid Format: The double value being passed may not be in a valid format. For example, it might contain characters that are not numeric or may have an incorrect decimal separator.
  Out of Range: The value might be outside the acceptable range for a double data type in SAP.
  Data Type Mismatch: There could be a mismatch between the expected data type in the CDS view and the actual data being provided.
  Locale Issues: If the system is set to a different locale, the decimal separator (comma vs. period) might cause the value to be interpreted incorrectly.
  
  Solution:
  
  Check the Value: Verify the value being passed to ensure it is a valid double. It should only contain numeric characters and a single decimal separator.
  Adjust Locale Settings: If the issue is related to locale settings, ensure that the correct decimal separator is being used based on the system's locale configuration.
  Data Type Validation: Ensure that the data types in your CDS view and the data being processed match. If necessary, cast or convert the data to the appropriate type.
  Debugging: Use debugging tools to trace where the invalid value is being generated or passed. This can help identify the source of the problem.
