Hi ,

I am new to SSIS,

I am trying to execute a batch script from Execute Process Task,i am passing 2 variables  like this

Src_Name='abcde'

Path =C:\ABCD\EFGH\IJKL\

when I excute the batch script from CMD prompt it works ,but from SSIS its saying Access Denied

the batch script does this -copy files from staging folder to source folder
