No suitable settlement rule found for object &

What causes this issue?

The settlement type in the settlement rule determines whether variance
calculation should be performed by period (settlement type PER) or
cumulatively (settlement type GES). You specify whether you want
periodic or cumulative settlement through the default values for the
default rule for the order type. The variances are only calculated for
orders whose settlement rule specifies the material as the receiver.
In your case, no valid settlement rule could be selected for order &V1&
for the following reasons:
No settlement rule was generated in master data maintenance.
The automatically generated settlement rule was changed such that it no
longer matches the requirements of variance calculation.

System Response

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

How to fix this error?

Check the entries in the settlement rule for order &V1&.
The settlement type is proposed through the default rule for the order
type. Check the entries for your order type:
For production orders and process orders, you can use PP1 (full
settlement) or PP2 (periodic settlement).
For product cost collectors, you must use default rule STR (with
strategy for tracing factor determination).
