situation in which operations for which provision has been made for a
separate confirmation from the MES are automatically confirmed.

System Response

The system terminates the saving of the order.

How to fix this error?

If necessary, choose a different control key for the relevant operations
of the order.

Procedure for System Administrators

You can check the settings of the control key &V1& in the
<DS:SIMG.SIMG_CFMENUOLPFOPJ8>Implementation Guide</>.
You can likewise influence the properties of this message in
<DS:SIMG.SIMG_CFMENOLPFOPJB>Customizing</> and thus suppress it if it is
not relevant to your business process.
