Answer / kumar

if you have not mentioned any initial values in the parameter
property sheet or if you have not used NVL function in your
query parameter, Obviously report will run without output,it
just display column headings.
otherwise (i mean if you have mentioned any initial values
in the parameter property sheet or if you have used NVL
function in your query parameter) report will run with output

Answer / muneer
