panel. A Cleanse transformation creates output fields based on the fields that you map in the
Field Mapping
tab.
The
Output Fields
tab displays the name, type, precision, and scale for each output field.
The transformation creates output fields in the following manner:
Cleanse asset with a single output
The transformation creates the cleansed field.
The output field name is the name of the target field appended by the name of the Cleanse transformation. For example, if you have a target field
Person_name
and you entered the name for the Cleanse transformation as
Cleanse_TX
, the operation returns the output field name as
Person_name_Cleanse_TX
.
Cleanse asset with multiple outputs
The transformation creates the cleansed fields and additionally any merged output field that you or another user configured in the asset.
The transformation attempts to adds the suffix
_Cleansed
to the name of each target field. For example, if you have a target field
FirstName
, the operation returns the output field name as
FirstName_Cleansed
.
If you created the cleanse asset in the current version of
Data Quality
, the transformation applies the suffix
_Cleansed
to all output fields. If you created the asset in an older version of
Data Quality
, the transformation may apply a different naming policy to the outputs. See
Rules and guidelines for output field names
for more information.
The merged output field names are the names of the merged fields that you configured in the asset.
You cannot edit the output field properties in the Cleanse transformation. To edit the properties, open the cleanse asset in
Data Quality
.
Rules and guidelines for output field names
You may create a cleanse asset in
Data Quality
and add outputs to the asset over time. This can impact the type of suffix that the Cleanse transformation applies to the output fields.
When you use a cleanse asset with multiple outputs in a transformation, verify that the field names meet your mapping requirements. You may need to map the output fields again to ensure that the transformation defines the field names in the manner that you expect.
Consider the following rules and guidelines when you review the output field names:
Some older cleanse assets supported a single output field in a single cleanse instance. If you add outputs to such an asset and you do not update the original instance, the Cleanse transformation applies the
_Cleansed
suffix to the newer outputs only. The transformation does not apply any suffix to the output in the original instance.
The Cleanse transformation applies this policy regardless of when you add the asset to the transformation. The transformation deletes a suffix from an older output field when you add an output in another instance and you do not change the original instance.
If you add an output to the original instance in any cleanse asset, the Cleanse transformation applies the
_Cleansed
suffix to all output names.
The Cleanse transformation applies this policy regardless of the age of the asset and regardless of when you add the asset to the transformation.
