Country/region &1 of validation rule &2 is inconsistent with policy.

What causes this issue?

The validation rule must have the same country/region as the policy that
the validation rule is assigned to. This message is displayed in any of
the following cases:
Case,,Policy,,Validation Rule
1,,Country A, for example 01-Germany,,Country B, for example 10-USA
2,,*,,Country B, for example 10-USA


Solution
The <LS>Consistency Check for Existing Objects with Configuration
Workbench </>(<AB>PYC_SUPPORT_CWB_CONS_CHECK</>) report can update the
country/region attribute for the validation rule based on the following
logic:
In Case 1, if the validation rule is used only in this policy, the
report changes the country/region of the validation rule to the same
value as the policy, which is 01-Germany in the above example.
If the validation rule is also used in multiple policies with different
country/region attribute, the report changes the country/region of the
validation rule to * - All Countries.
In Case 2, the report changes the country/region of the validation rule
to * - All Countries.

How to fix this error?

(Recommended) If you want the report to apply the abovementioned
solution for you, choose <LS>Apply Solution </>in the application
toolbar bar on the <LS>Display All Convertible Configurations </>page of
the report.
If you want to change the configuration by yourself, you can manually
edit the country/region attribute in Configuration Workbench or in
Customizing activity <LS>Define Check Types </>(under Customizing for
<LS>Payroll -> Payroll: International -> Payroll Control Center ->
Payroll Control Center Configuration Simplification</>).
A validation rule is also called a check type in the Customizing
activity.
