Getting error SAPUser : Write permission denied for value 'Password' while doing password reset

Hi All ,

We are trying to implement password reset functionality for SAPUser table  in version 8.1.2 and getting the above mentioned error in the update process step .

Another thing which we have observed that the password column in object  browser says that 'caneditisdisallowedby' : SAP.Customizer.SAPUser . This is something new in version 8.1.2 . 

Can anyone please suggest , is there any other way to reset password for SAPUser as per new version ?

Thanks in advance .
