A cleanse asset comprises one or more cleanse instances. Each instance represents one or more input fields for which the asset specifies a set of cleanse operations.

You can add multiple cleanse instances to an asset in Data Quality, so that a Cleanse transformation can apply multiple cleanse operations to different sets of input fields with a single asset.

If you select a cleanse asset that specifies more than one input field, you must understand the asset configuration and know the types of cleanse operation that the asset will perform on each input. The Cleanse transformation does not identify the instance on which each asset input originates. If you define multiple instances on the asset in Data Quality, make a record of the instances to which each input belongs. Use the record as a guide when you connect the asset inputs to the transformation input fields.
