Default values in IDT Prompt

I have to display in the prompt for eg: 201401, 201402,201403...201412 so that user can select one of them

@prompt('Enter the From  Fiscal Year and Fiscal Month:',A','',Mono,,non_persistent,year(getdate())*100 +FISC_PER.FISC_PERIOD)

Have to include year(getdate()) *100 +FISC_PERIOD.FISC_PERIOD in the prompt in IDT
