Production orders can only be distributed through release of order

What causes this issue?

Production orders that are relevant for distribution to an MES are
automatically distributed to this system upon order release. There is no
provision for distribution via the transaction <ZK>Execute Data
Replication</> (DRFOUT).

System Response

The system terminates the distribution.

How to fix this error?

If you want to redistribute an already distributed production order to
the MES, you can make a change to the order. When the updated order is
saved, it is then sent to the MES again.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
