I'm trying this method: (can it be done in v. 12.0?). I'm trying to apply it through Scheduled Actions. Because "automated actions" doesn't appear any more.

Technical Settings ---- Automation ----- Automated Actions

Just Select the model in your Case "Purchase Order"
Action "Send Email"
Select the Desired Template
Select the Condition when you want this action to happen, for example Creation. So this will send an email when a New Purchase Order is Created.

I tried following the steps as pointed out above:

Just Select the model in your Case "Purchase Order"

And it works for me.

Thanks

If you want to do it without overriding the confirmation method, you can create an automated action that check if the sales order or the purchase are validated and send an email.
