Using status data to identify exception records

To generate status values that identify exceptions, configure an action with a status value of Invalid and use the exception properties to indicate why the records meet your exception criteria. Users who analyze the data in downstream processes can use the data that you add to find the exception records and to understand why they qualify as exceptions.
For example, you might decide to examine the output from a mapping that performed duplicate analysis, on the basis that the output may contain additional duplicate records. Let's say that the deduplicate asset in the mapping applied a match threshold value of 90% to the records.
You decide to identify the records that retuned a match threshold value of 89% in the deduplicate output. You define a rule statement that reads the Out_LinkScore field from the output and updates any records with a score between 89% and 90% as Invalid. Additionally, you define exception properties to add Major as the priority value and Potential Duplicates as the descriptive text.
    1Select the primary rule set in a rule specification.
    2In the rule set properties, click Rule Logic.
    3Click Add Rule Statement.
    4Select an input of type float for the rule statement.
    5Select an operator to validate the results of the condition analysis.
    is greater than or equal to
    6 Select the type of condition to apply to the input.
    7Enter the value to compare to the input data. In this case, enter 0.89.
    8Select Add Condition in the rule statement menu.
    The rule specification adds a condition under the current condition and creates an AND relationship between the conditions.
    9Select the input that you added in step 4.
    10Select an operator to validate the results of the condition analysis.
    11 Select the type of condition to apply to the input.
    12Enter the value to compare to the input data. In this case, enter 0.9.
    13Select the type of action to apply to the data that satisfies the condition logic.
    14Configure the exception properties to add data that describe the status of the record.
    15Save the rule specification.
