Content

The seeded Benefit Extract for FSA data is not fetching the Coverage amount, SO I have written a Fast formula to get the amount. But when the extract is run the Value is always 0 and no of the records fetched is decreased. Not all records are coming. I have attached the formula, could anyone review and let me know what is the issue is.

Thanks!!
