SQL Scripts for Microsoft Dynamics GP: Select Workflow Comments for Work Status Batches

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 will return all unposted batches and the workflow approval comments which have been entered; it was used within a customisation of workflow in Dynamics GP which allowed the returned comment to be added to the workflow approval notification emails.
