Hello Abhilash Kumar ,
Thanks for your reply ,
am thinking this is the correct way ,
I tried to use the function as you suggest , what happen then is no data will come in the report ,
so am suspect that i may had some mistake in the function syntax ,
here is the formula I have :
{Command.Invoice Date} in {?Date} to {?To Date} and
{Command.SeriesName} = {?Department} and
{Command.DocNum} = {?DOCUMENT NO} and
{Command.SlpName} = {?Sales Emploee}
if you can give me an example of any of the parameter so I can understand better ,
what I did is using if hasvale ( {?Date},{?To Date} ) then {Command.Invoice Date} in {?Date} to {?To Date}
