Issue:
User had mistakenly added the wrong product Serial Number for two products
i.e. For Product 'A' user added SN '456' and For Product 'B' user added the SN '123'.
However, the the correct configuration is Product 'A' should have the SN '123' and Product 'B' should have the SN '456'.
Resolution:
User needs to adjust-out both Items Serial Numbers and then adjust-in the correct SN for the corresponding Items.
