Default a string value in DMF AX 2012 (Instead of creating a generate methods or hardcode in design)

Last week when i was doing an import for employee entity, my analyst told that customer won't provide email description in import file and it was just a textual description which was common throughout my DMF import. First i thought to write a generate method (which is again a time consuming option), then i found an easier way to do it. DMF has build in functionality to pass a constant string/default value. To do that

Steps

1. Go to Processing groups form.
2. Select the entity for which you have pass default value and click Entites.

3. In the Entites screen select modify source mapping.

4. Follow the step in below image

5. Provide default staging value in below screen

6. Click Ok.

That will add your text value in staging.

Happy day :)
