Error While running Sync-Tenant in NAV 2015

Hi Experts,

We are getting the following error while running the Sync-Tenant while upgrading to NAV 2015

The following SQL error was unexpected.

Invalid object name 'XXXX.dbo.company$xxxxx'

or the below error

The application object of type Table with ID xxxx has been compiled with an old version of the Microsoft Dynamics NAV Development Environment Client.
The object must be recompiled to work with this installation of the Microsoft Dynamics NAV Server. If you have recently upgraded the database, we recommend that you
build all objects using the Build Server Application Objects menu item in the Tools menu.

The table for which the above error is occurring does not exists in NAV database or could not be found in SQL.

Could pleas help me with the above error as i cannot go ahead and run the upgrade step2 .

Thanks in Advance
