Multiple attachments in Send Email Smart service

Hello All,

I have created a process which will generate multiple PDF documents using PDF Doc from Template smart service. At the end of the process Send Email smart service will be called to send the generated PDF to the customer. 

In Send Email Smart service attachment session, i gave expression like (=pv!welcomeLtr;pv!repaySchdlepdf;). But i'm getting the first attachment only in the email. I have verified the process variable , document is created and stored in the process variable as well as in the folders as well.

Could you please help us on this issue?

Regards,

Ramesh
