Problem with importing ds file and duplicate the application

Problem with importing ds file and duplicate the application

I took the Application(which is shared ) back up as .ds file and i login as a another user and i imported the .ds file  then i am getting the error


"Problem encountered while creating the application
api functions can be created only by application owner"


And if i create a duplicate of that application some functionality is missing .

Can Any one help me out

Thank you
