Periodic settlement not allowed in collective orders

What causes this issue?

In Customizing for the &V1& order type it is defined that orders are
settled periodically (default rule PP2). However, this is not allowed
for subordinate orders in a collective order.

System Response

The system sets the default rule for this collective order to PP1
regardless of what is specified in order type &V1&. The collective
order is then subject to the full settlement

How to fix this error?

If you want to prevent this message from appearing in the future when
you create a collective order, you have the following options:
Use an order type for collective orders that uses the full settlement
(default rule PP1).
Change the Customizing settings for the order type used (&V1&).

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