Consider the following rules and guidelines before you run mappings, tasks, or workflows to generate consistent masked output:

Use substitution masking rules to generate consistent masked output.
The masking rules must use the same dictionaries.
The Repeatable option must be set to ON.
Use the same seed value.

Substitution masking rules use values from dictionaries to create masked output. The default dictionaries on

Informatica Intelligent Cloud Services

and on-premise Test Data Management are the same. When you use the same substitution rule, the workflow uses the same dictionary to substitute source data. The same seed value therefore ensures that the same substitute value is used for all rows provided the dictionaries are the same.

On

, the dictionary files are available at:

<Secure Agent installation directory>\apps\Data_Integration_Server\data

In on-premise Test Data Management, the dictionary files are available at:

<Informatica installation directory>\server\infa_shared\LkpFiles

The Repeatable option must be set to ON to ensure that the task or workflow repeats dictionary values for the same source value.
