You can configure properties on a parse asset that determine how a mapping that includes the asset will read, write, and process data. To view the properties, open the Parse Properties dialog box from the Actions menu on the Data Quality toolbar.
The following image shows the properties:
You can set the following properties:
Detailed Overflow
Determines whether the parsing operation creates an Overflow field for each step in the asset at run time. Select or clear the option in Custom mode.
When you select the option, the transformation writes overflow data to a separate field for each step in the asset. When you clear the option, the transformation writes all overflow data that the asset identifies to a single field. The option is cleared by default.
The Detailed Overflow option does not apply in Pre-built mode, as the asset specifies a single parsing operation in Pre-built mode.
Input Field Delimiter
Specifies the delimiter that the parsing operation recognizes when you parse data with a dictionary or regular expression. Set the option in Custom mode. Use the Select option to select the delimiter or to add a custom delimiter. You can select one or more delimiters. The default input delimiter is a character space.
Output Field Delimiter
Specifies the field delimiter that the parsing operation applies in any output field when you parse data with a dictionary or regular expression. Set the option in Custom mode. Use the Select option to select the delimiter or to add a custom delimiter. The default output delimiter is a character space.
Maximum string length
Specifies the maximum number of characters that a parsing operation can read or write in an input or output field. You can set a maximum string length of 10,000 characters. The default maximum length is 255 characters.
