Reference characteristics will not be updated

What causes this issue?

Reference characteristics are used.

System Response

In the parameters for the order type, it is specified that reference
characteristics for co-products should be used.
If changes are made at this point the system does not perform
configuration. Therefore the reference characteristics are not updated
either.

Procedure for System Administrators

parameters for the order type.
