Parse transformation

Parse transformation

The Parse transformation adds a parse asset that you created in
Data Quality
to a mapping.
A parse asset defines a set of operations that identify tokens in an input field based on the content or structure of the token. In a parsing operation, a token is a discrete word or string.
The Parse transformation parses the tokens to output fields that the asset specifies. When you configure the transformation, you map an input field to the appropriate target field in the transformation. When the mapping runs, the transformation searches the input field for tokens that meet the parsing criteria and writes the tokens to the associated output fields. If the transformation can identify an input data value but a defined output field is not available, the transformation may write the value to a predefined field for overflow data. If the transformation cannot identify a value in the input data, it may write the value to a predefined field for unparsed data. The asset that you add to the transformation determines the number of overflow and unparsed data fields that the transformation creates.
A Parse transformation is similar to a Mapplet transformation, as it allows you to add data transformation logic that you designed elsewhere to a mapping. Like mapplets, parse assets are reusable assets.
A Parse transformation shows incoming and outgoing fields. It does not display the logic that the parse asset contains or allow to you edit the parse asset. To edit the parse asset, open it in
Data Quality
.
The transformation is not certified for serverless runtime execution.
