Select shipments with the same delivery split profiles

What causes this issue?

You have attempted to execute the delivery split for several deliveries
from different shipments. The shipments have different total statuses
(not yet planned / already planned). However, for these total status
values there are different delivery split profiles stored in the
shipment type.

System Response

The split transaction can only be executed with a split profile. It is
therefore terminated by the system.

How to fix this error?

Either select only deliveries in shipments that have the total status
"In planning" or are not currently planned. Then execute the split
separately for both groups of deliveries. Deliveries that are not
assigned are considered to be "in planning".

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.
