Settlement rule maintenance is not possible (see long text)

What causes this issue?

No <DS:GLOS.settlement_profile>settlement_profile</> was found for the
object currently being processed (for example, order, cost object).
Additionally, you cannot enter a settlement profile, as you have no
authorization to change the settlement parameters.

System Response

It is not possible to change the settlement rule.

How to fix this error?

You can either request maintenance authorization for settlement
parameters or have the settlement profile entered in Customizing.
If the object you are currently processing is an internal order, then
the maintenance authorization for the settlement parameters is given
through the
<DS:UO.K_ORDER>"General_Authorization_Object_For_Internal_Orders"</>.
Usually, a settlement profile is entered in Customizing, which is then
automatically copied when you create a settlement rule. For orders
(apart from sales orders) this occurrs in the order type.
