Execution Of SSIS Package From Stored Procedure

Hello friends!
I have one query regarding execution of SSIS package through Stored Procedure.

I have created SSIS package which extract data from database and put that into various text files.Here I am using two global variables one is for Department ID and another is path where I wanna to place my text files as per departments.When I ran it through command prompt it works fine but now I want that dtsx package to run from stored procedure with same input parameters

when i searched on line i got this solution

Declare @FilePath varchar(2000)

Declare @Filename varchar(1000)

Declare @cmd varchar(2000)

set @FilePath = 'C:setupSSIS PackagesSSIS Package File Extract DataSSIS Package File Extract Datain'

set @Filename = 'DataExtract.dtsx'

select @cmd = 'DTExec /F "' + @FilePath + @Filename + '"'

print @cmd

exec master..xp_cmdshell @cmd



but when i execute it i got error like
