hi Pritesh,
if there's the option of getting rid of the parameter then you could use YEAR(CURRENT_DATE) instead...i.e.
FBD.FISCAL_YEAR = YEAR(CURRENT_DATE)
however, if you need to leave the query as it is, with a parameter, then the only way to do this is to create a new report and Insert > your existing report as a Subreport. then create a formula that will act as a link to the subreport's parameter. formula syntax would be
year(currentdate)
