Rules and guidelines for overflow and unparsed data fields
The parse asset configuration determines how the associated Parse transformation creates overflow and unparsed data fields at runtime.
Consider the following rules and guidelines about the overflow and unparsed fields:
When you configure an asset in Custom mode, the
Detailed Overflow
option determines how the Parse transformation creates overflow fields. If you clear the option, the transformation creates a single overflow field for all overflow data from the asset. If you select the option, the transformation creates an overflow field for each step in the asset.
Find the Detailed Overflow option in the
Parse Properties
dialog box when you configure the asset in custom mode. Open the properties from the Data Quality toolbar. The option is cleared by default.
When you configure an asset in Pre-built mode, the locale that you select determines whether the Parse transformation creates an overflow field. The transformation creates an overflow field when you set the locale to Brazil or Portugal. The transformation does not create an overflow field in other locales.
A Parse transformation creates a single field for all unparsed data when you configure the asset in Custom mode.
The locale that the asset specifies in Pre-built mode determines whether the Parse transformation creates an unparsed data field. The transformation does not create an unparsed data field when you set the locale to Brazil, Canada, Portugal, or the United States.
