MAX_OTHER_COLUMN

The MAX_OTHER_COLUMN rule selects a column value from a record that contains the highest value of the specified column. The MAX_OTHER_COLUMN rule uses case-insensitive lexicographical ordering to find the highest value.

For example, use the City value from a record that contains the highest donation amount.

The following table displays a sample cluster and indicates the rule-level preferred record:

Cluster ID	Employee Name	City	Donation Amount	Department	Comment
1	John Smith	San Francisco	1000	Sales	Row-level preferred record
1	J Smith	Redwood City	1900	Human Resources
1	John Jr Smith	Seattle	800	Support

The following table lists the preferred record with the preferred column value based on the MAX_OTHER_COLUMN rule applied on the City column:

Cluster ID	Employee Name	City	Donation Amount	Department	Comment
1	John Smith	Redwood City	1000	Sales	Column-level preferred record

Redwood City is the preferred column value because it is part of the row that contains the highest donation amount.

Use the following format to configure a MAX_OTHER_COLUMN rule:

<ColumnRules>   
   <ColumnRule name="<Rule name>" rule="MAX_OTHER_COLUMN" columnName="<Primary column name">
      <ReferenceColumn columnName="<Reference column name>" />
   </ColumnRule>   
</ColumnRules>

The format uses the following parameters:

Rule name: Unique name for the rule.
Primary column name: Name of the column based on which you want to configure the rule.
Reference column name: Name of the column in which you want to find the highest value. The consolidation process identifies the record that contains the highest column value and then uses the primary column value from the selected record as the preferred column value.

The following sample MAX_OTHER_COLUMN rule indicates to use the City value from a record that contains the highest donation amount:

<ColumnRules>
   <ColumnRule name="OTHEREQ_RULE1" rule="MAX_OTHER_COLUMN" columnName="City">
      <ReferenceColumn columnName="Donation Amount" />
   </ColumnRule>
</ColumnRules>
