Semantic value &1 is invalid.

What causes this issue?

You see this message because this validation rule has the semantic
category <AB>PYD_NEED</> (Needs Data) with the specified semantic value,
but there is no validation rule that <ZH>provides </>data for it: that
is, validation rule of semantic category <AB>PYD_CKFLTR</> (Represents a
Check-Result-Filter Data Source Type) with the same semantic value.
<ZH>Background</>
One validation rule Y can use another validation rule X as filter to
suppress the check results of Y. As a result, if an alert detected by Y
is already raised by validation rule X, the same alert will not be shown
by Y.
Prior to Configuration Workbench, this is implemented in Customizing
activity <LS>Define Check Types </>(under Customizing for <LS>Payroll ->
Payroll International -> Payroll Control Center -> Payroll Control
Center Configuration Simplification</>.)
For validation rule X, which is used as filter, assign the semantic
category <AB>PYD_CKFLTR </>and any pairing semantic value (for example,
ABCD).
For validation rule Y, which uses validation rule X as filter, assign
the semantic category <AB>PYD_NEED </>and the same pairing value (ABCD
in this case).
RESET N1
In Configuration Workbench, this is implemented by configuring alert
dependencies for validation rules:
Enable validation rule X as a filter by selecting the checkbox <LS>This
validation rule can be used by other validation rules to suppress raised
alerts </>on the <LS>Alert Dependencies </>tab page.
Add validation rule X in the alert dependencies of validation rule Y on
the <LS>Alert Dependencies </>tab page.
With Configuration Workbench, you no longer need to enter a pairing
value, but the validation rule ID is used automatically as the semantic
value for <AB>PYD_CKFLTR</> if the validation rule is used as a filter.


Solution
The <LS>Consistency Check for Existing Objects with Configuration
Workbench </>(<AB>PYC_SUPPORT_CWB_CONS_CHECK</>) report can update the
configuration by removing the semantic category <AB>PYD_NEED </>and the
semantic value from the validation rule.

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 alert dependencies for relevant validation rules in Configuration
Workbench or edit the semantic values of relevant validation rules in
Customizing activity <LS>Define Check Types</>.
