Yes if I use an email field from BO. I was trying to use a free text field for requestor to enter whatever email address and send approval request to that person's email. I guess I have to use the email from BO.
That option on the approval block allows to select fields from the ServiceReq BO or fields on the Request Offering. For instance, in that example i'm sending an approval to what email address the user enters. I believe the approver would need a contact setup within Heat before the approval would send though.
I changed the free text field to "Email Text Box" and added a drop down box.
On the approval block you see the request offering fields first, then the BO fields are separated by a space.
