Hello Expert,

I recently updated the Display Name in our lower environment for only US employees, and I can now see the updated name format reflected on the Springboard.

Before I proceed further, I wanted to check with the community.

Is there any functional or technical impact of changing the Display Name format on other areas of the system? For example, does it affect approvals, workflows, person search, reporting, security, or any downstream integrations?

If anyone has experience with this change or can confirm the scope of impact, your insights would be greatly appreciated.
