Data Masking Task

Effective in the Fall 2016 release, you can select a dictionary from the Dictionary File field in a custom substitution rule. In the Select Dictionary File dialog box, you can add or select a flat file dictionary connection and select the dictionary file. The Dictionary Connection field is removed.
Previously, you had to select the dictionary from the Dictionary Connection field.
