The most common way to start/stop production runs is by using the Production plan page in Operator tools.
The simplest set-up is to use article runs.
In an article run, the operators start and stop articles without a link to an order number, planned start time/end time or ordered amount.
If you need to follow up an order or use RS Production to report back to ERP, you need order runs.
If you run an order run, you can pause it and return to the same order. Here the order will be registered as several separate runs.
