1. Open the Supplier account and click on Purchasing > Product range.
2. Open the  Supplier item by double-click.
3. Click on the expand triangle of the linked master item   to open the options for the item and select  Delete assignment.
4.  Search other master items to link in the same way, or directly open a  New master item.
5.  Save your input by clicking on the icon in the top left-hand corner of the input window.
