On Loads form, Action pane, there is the Reverse work functionality.

This functionality works fine when there is only one Work Id linked to a Load line.

If more than one Work IDs were created for a Load line (due to work template/business requirements), Reverse work functionality returns the following error:

Cannot reverse work because loads have already been picked for the sales line. Use Reduce picked quantity instead of reversing the entire load.

Use reduce picked quantity line by line in large organizations is not an option as there might be many many lines on a load.
