Hello All,

I have a requirement to export data form as a csv file, using groovy scripting I'm able to do so, but i need to export a specific intersection depending on certain data values, Example: i have a column for hiring status with a data type smart list, this could contain two values approved or unapproved, i need only to export the intersection with an approved data value, is it possible using groovy to filter based on data value?
