Recently I had to create a mail process where I used the first time the “new” E-Mail-Templates. The following Blogs helped me do this:

In my case it was not possible to fetch the data via CDS View, I therefore had to manually fill the variables. Following a simplified version of my code.
You must create a CDS View, as this is the structure in which the variables defined in the mail text are mapped to, even if you do this manually.
define view entity ZMAIL_MY_TEMPLATE as select from pa0001 {
key pa0001.pernr,
pa0001.ename,
cast ( '' as abap.char( 20 ) ) as custom_field // this way you can add a field, that does not exist in the selected table
}
This is just one way, how you can manually fill the variables. Other ways are possible using the class cl_smtg_email_api. I choose the method render_w_data because it returned the mail text, and you manually can do additional changes to the mail text, like adding HTML-Table content, which otherwise gets “escaped” when filled via a replacement variable.
