From version 23.6.0 the fields for "Upper reasonable limit", "Upper limit", "Nominal value", "Lower limit", and "Lower reasonable limit" are no longer mandatory. The reason for this change was because the fields were rarely used.
This tab will let you choose what limits from different part information that activates on now running orders. The part information is collected from "Client" -> "Administration" -> "System settings" -> "Parts" - > "Parts 2 - Parts 11". Here you can read more about how that works. If there is no value, or if the text in the part information is not convertible to a decimal, the row will finish as an anomaly. The system will also display an error message to confirm the anomaly.
