Personnel Administration

Hi Guru's

We got a requirement from client to restrict the access in portal for employees not allowing them to change their name and other personal details

we checked with authorization they said they cant restrict the access particularly for any field. we discussed with portal team also they said this screens comes directly from back end, so nothing they can do from their end too.

so my questions are

From functional point of view can we restrict the fields? or should i need a help of abaper to complete this.

Please suggest me

Thanks

Sriram
