Error in configuring management reporter

When configuring management reporter I am getting error as :

 An error occurred while configuring SQL change tracking. Check your deployment log for details.
Cannot enable change tracking on table 'RetailTerminalTable'. Change tracking requires a primary key on the table. Create a primary key on the table before enabling change tracking.

I have tried these two solutions.
