How to pass comma (,) as the delimiter when we are getting comma in the actual data in source file

Summary:

The HDL Fast Formula has been defined to read a csv flat file (comma as delimiter).

While testing we faced a scenario where we are getting comma in the actual data. The data (containing commas) is enclosed in double quotes in the source file. Ideally in such cases since the field is enclosed in double quotes, entire text should be treated as a single position.

However transformation FF while reading the file is treating the comma contained in data also as a delimiter, because of which values for various positions is changing and FF logic is not working as expected.
