title: Error while calling DTS package in to the control flow
body: <p>Have created DTS package for file transformation and i saved as a File system. Now am trying to call that package using "Execute Package Task". I gave all connections, saved and closed the project. When am  re-open the project am trying to execute, while executing it will automatically calls that package and allows to execute. But while executing it will shows error  that the packages "<strong>already opened</strong>"... Task itself open the package then how it will show this error, because of this my entire package will become failed.. Can anyone explain anyway to solve this problem?</p>
