MODAL_EXACT

MODAL_EXACT

The MODAL_EXACT rule selects the row that has the highest number of columns with the most frequent non-blank values.
The following table displays a sample cluster and indicates the preferred record for the cluster based on the MODAL_EXACT rule:
Cluster ID Employee Name City Age Department Comment
1 John Smith New York 31 Sales Row-level preferred record
1 J Smith New York 31 Human Resources
1 John Smith Seattle 30 Sales
The MODAL_EXACT rule selects the first row as the preferred record because it has four columns with the most frequent non-blank values.
Use the following format to configure a MODAL_EXACT rule:
<RowRules>   
   <RowRule name="<Rule name>" rule="MODAL_EXACT" order="<Execution order>">
   </RowRule>   
</RowRules>
The format uses the following parameters:
Rule name
Unique name for the rule.
Execution order
Optional. Order of execution for the rule. Use an integer value for the order of execution. If you do not specify the execution order, the consolidation process runs the rule based on the sequence of rules listed in the consolidation rules file. If you specify the execution order for a rule, you must specify the execution order for other rules.
The following sample uses the MODAL_EXACT rule:
<RowRules>
   <RowRule name="rowlevel7" rule="MODAL_EXACT" order="1" />
</RowRuless>
