Dear Caroleigh
I tried to keyed-in the new e-mail. When I push the save button it does not change the new e-mail. The red message appeared stated that: The E-mail Id has belonged to the another user. I will send e-mail to the sapnetwork@sap.com to help me in resolving this issue. Thank you very much for your kind support and attention.
Thank you.
Regards
Hafizi
