I want to do from the report function not query.
how can i do that

> I want to do from the report function not query.

I'm not quite sure what you mean by this. I supose this means that you don't want to do it in MDX, but you don't mention what you are using as a reporting front end. In psuedo code what you would do is

1) subtract the day number from the date ( this should give you the last day of the previous month)

2) add 1 month to the date you got from the first step.

Can you please give a working example ?

Do you know about any thing about date subtract in SSRS
Like I have 2/15/2007 as input parameter from report I want's to subtract 15 days and result should be like 1/31/2007

I have get the day from the date and i can add a month also in the date But I cant' find any thing about how to subtract days from the date and result should be another date

You should be able to add the following in the code section of your report and then just call this function.

function GetLastDayInMonth(dt as DateTime) as DateTime

return dt.AddDays(-dt.Day).AddMonths(1)

end function
