Customer Account DFF - Read only personalization

Hi,

We opened about 10 DFF's at the Customer Account level. (Customer Information (1) DFF).

Out of these, we want only 1 DFF to be set as "Read Only" for most of the AR Responsibilities. How can we achieve this?

This is what I did:

1. Customers - Customers
2. Pull up a customer. Go into Account details
3. Click Personalize Create Account link
4. Select "Flex: (ActFlexField)" and click on update icon
5. Set Read-only to True for a responsibility.

Once this is done, all 10 DFF"s become Read only for the above responsibility

Any help is appreciated

Thanks,

Siva
