I am having a problem duplicating items using the same item code. So here is how I can replicate the problem.
Edit an existing item and rename item code. Save and Duplicate item. Now in the duplicated item, I enter the original item code and save. Once the item is saved, I can no longer edit the item. Clicking on the item in the list does not bring me to the item edit window. I suspect some error is occurring on the server. This is installed on my own server and not running in the cloud.
Perhaps there is an easier way to do what I am trying to accomplish. Currently all my items have “Maintain Stock” checked. I no longer want to track inventory so I would like to uncheck this. Because I can’t change an existing item, I was going to go through and duplicate all my existing items and uncheck “Maintain Stock” and then re-assign the original item code to the newly created item.
