I have a scenario that when billing is generated in system. Invoice should be send through mail to Person Account Email. I am doing this via workflow. In workflow I have a VF email template which contain component that have all related data like name, address. that has already done. but problem is related to attachment I am not able to attach existing attachment in email template. attachment is already generated via DDPs. I want to avoid create new component with data and render as pdf.
Is there any way to add existing attachment to email via workflow. Please anyone Guide me for the Answer.
