I was asked by a client to change the Sales Order status “Completed” to “Shipped” because they found “Completed” misleading. (Completed orders may or may not have been invoiced.) I didn’t find a way to change the workflow status description in the customization workflow, so I looked for a different option. I changed it in the Translation Dictionaries, which I find even simpler. This value was used in multiple places and I could choose to change it globally or by screen. In the example below, I changed the status description for Sales Orders but left it as Completed for Purchase Orders.
Hopefully this is helpful for someone looking to make a similar change.
