Currently, most of our attributes are mapped from our on-premise Active Directory. However, we have a scenario in which we would like to update an Okta attribute with an expression based on existing attributes. For example, we would like a custom Okta attribute called "fullName" to pull the Okta user first name and last name together. Documentation seems to all reference mapping from other apps, not within Okta itself.

Hi @7aydp (7aydp) , Thank you for reaching out to the Okta Community!
The attribute mapping feature can only be used to map attributes from AD (or other apps)to Okta
example for your use case:
appuser.firstName + " " + appuser.lastName
OR
from Okta to downstream apps
example for your use case:
user.firstName + " " + user.lastName
but not from Okta to itself.
Both way of using mapping should ultimately satisfy the need to use that value, but I may be misunderstanding your use case/requirement.
If my answer helped, remember to mark it as best to increase its visibility for other members of the Okta Community who might have the same questions as you.
Hope my answer helps!
