Deletion of Email entry is not possible in MDG-S/C ver 9.0

Hi Team,

We have implemented the E-Mail Notes functionality using the below link. When there are multiple addresses and multiple mail ids, it is not getting deleted. Even after CR activation, the email address comes back. Please let me know if anyone has the solutions

Make the standard feature of Email Notes/Remarks available in MDG S/C UI.

Thanks,

Sun.
