SQL Scripts for Microsoft Dynamics GP: Update Items Default Purchasing Unit of Measure from CSV

This script is part of the SQL Scripts for Microsoft Dynamics GP where I will be posted the scripts I wrote against Microsoft Dynamics GP over the 19 years before I stopped working with Dynamics GP.

This script updates the default purchasing unit of measure on items from a CSV file. It will validate the item during the import and if there are any errors these will be presented to the user and the data will only be updated when there are no errors.
