System Response

The system issues a warning if production order &V1& is not relevant for
distribution to an MES.
However, if production order &V1& is also relevant for distribution to
an MES or has already been distributed there, the serial number &V2&
cannot simply be assigned to the current order. Depending on the system
setting, the system issues a warning or an error message.
