custom attributes are empty--Need to update the value

Under what circumstances do you need something written to these attributes - for example, on user create?

Are the values placed there always the same or do they depend on something - for example, the Department of the user.

One way or another, you can probably use a combination of provisioning policy and/or a change workflow to populate these.

Need more information on your use case.

well, as of now i need for the existing users and for newly created users as well. the value will be the same at every time as it is requirement of another application.
