This screen is used to create a new Job Item to use when Invoicing or Crediting Customers.
You would need to have set up the Job Items Group before using this screen.
This screen is used to set up the Groups, which are assigned to the Job Item. If you do not want to use the Group, then you can Archive it.
This will allow you to set up the Nominal Code for the Group and this is used for the Job Item. Please make sure these exist as there is no in built validation.
