I've been using FM SO_NEW_DOCUMENT_ATT_SEND_API1 to send an email with a SmartForm attached.
The thing is that I want to change the sender_address but in this function I'm not able.
Investigating the code of this FM, I've founded out that this one calls SO_DOCUMENT_SEND_API1. That's all the things it does. At this point I am able to change the sender
I really don't know why I can not make the FM work.
Can anybody help me?
