Hi Akshaya
I don't believe adding a DUNS number from UI or otherwise on a profile, will auto-register that profile for DnB Monitoring.
If there are no custom background processes running at your end to auto-register a profile, then you will need to do this explicitly via the 'Register Single Entity' API - Registering Single Entity
Additionally you can also add a button on the UI, similar to the other DnB Get Match and Get Company Profile buttons, to enable users to register a profile directly from UI after the DUNS number is available -

Thank you.
