When you configure a Rule Specification transformation in a mapping, you first select the rule specification asset that contains the logic to include in the mapping. Next, you configure the incoming fields and the field mappings. Then, you verify the output fields.
To configure the transformation, complete the following tasks:
Connect the Rule Specification transformation to a Source transformation or other upstream object.
tab, select the rule specification that you want to include in the transformation.
The following image shows the options that you use to select the rule specification:
tab, configure the incoming fields.
By default, the transformation inherits all incoming fields from any connected upstream object in the mapping. You can define a field rule to limit or rename the incoming fields.
tab, configure the field mapping options to connect the data from the incoming fields to the target fields on the rule specification asset.
The rule specification inputs might already reflect the names of the input fields in the data. If so, you can use the
Verify the rule specification output fields on the
You can optionally rename the Rule Specification transformation and add a description on the
tab. You can also update the tracing level for the transformation on the
tab. The default tracing level is Normal.
Consider the following rules and guidelines when you use a parameter to identify the rule specification that the transformation uses:
If you use a parameter to identify the rule specification, you must use a parameter to define the field mappings on the
tab. The parameter must be of type
If you use a parameter to identify the rule specification, any downstream object in the mapping that connects to the Rule Specification transformation must be completely parameterized.
If you update an asset in
after you add it to a transformation, you may need to synchronize the asset version in the transformation with the latest version. For more information about data quality asset synchronization, see
Synchronizing data quality assets.
