MDM questions

Hi MDM community,

Some questions :

1) If we create a user,how do we prompt a user to change the initial password

2) I have brought in some data into MDM.Now I want to apply my matching strategies on it.When I do it only shows in the top section of the screen.Why

does it not show in the matching tas in the lower half of the screen.My matching,merge tabs in matching mode is empty ?

3) Also for success,it shows some -2345556666 some number ,why ?

4) If I make a field READ only it does not make the field GREY in the data manager.

Appreciate your inputs.

Thanks.
