Pick first name from list

The Pick first name from list masking activity allows you to mask table columns by replacing them with a value from the first name picklists.

Table of contents


To use the Pick first name from list masking activity, it must be placed inside a table masking activity or a similar activity that iterates over data. Once placed, you can choose the property you want to mask, and then select the type of data you want to replace it with. Furthermore, you can specify what subset of picklist data will be used to get the replacement values from.


Let's assume we want to mask first names in the Customers table. We can do this by first placing the Customer masking activity, and then placing the Pick first name from list masking activity inside it. Then, we choose the FirstName column, and for the type of data to replace it with, we choose FirstName. We leave the picklist declaration as it is.
