System Response

It is not possible to copy firm simulative orders for materials
directly produced. It also does not make sense to copy firm simulative
orders because:

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

No simulative planned orders with direct production exist for this
material in the planning scenarios.
Although firm simulative planned orders could exist for this material
in planning scenarios without direct production it would not be
possible link the planned orders to higher-level planned orders. This
is because when copying them the system converts them to planned
orders not for direct production in the net requirements segment. This
is not consistent with the settings specified in the material master.
Due to this, it is generally not permitted to copy planned orders for
material &V1&.
