Making fiscal periods dynamic in financial reports

run in background using variants. Is there a way to make the fiscal period select option 'dynamic' so that the variant can determine what the current fiscal period is?

When you create a variant, you have the option of using Selection Variables. If fiscal period is a date, then you may be able to use one of the supplied date calculations. Otherwise, you should write a program to update TVARV with your own variable, and use that as a selection variable.
