  The purpose of the paper is to rectify a series of errors occurred in [2],
[17], [20] for a particular situation. To get a fruitful solution and to
overcome the issue, we introduce a new form of set sharing namely restricted
set sharing, which is stronger than the usual one. We manipulate the newly
introduced notion in this specific section of literature to resolve all the
complications. Not only that we have subtly used the same sharing form to a
well known unique range set [3] to settle a long time unsolved problem.
