Some guidelines how to you can setup faxing from SAP :-
You will need an additional software to be installed.
The best way to do this is to get a standard desktop PC with a modem
attached. Buy a copy of Winfax 10 (its only about $100 to buy.)
When you have Winfax setup and working locally, install SAPLPD (put it in the
startup group so its loads on startup).
WinFax will create a shared fax on the PC (For e.g. IFAX).
When this is done create a printer/Fax in transaction SPAD.
Device type = SAPWIN Rel.4.x/SAPlpd
Device class = Fax
Host Spool access method = S;print using SAP protocol
Dest. host = PC IP address
Host printer = Shared fax name on PC(i.e IFAX)
Make sure you have all the lasted SAPLPD + dll's
After that is done create the locations in transaction SCOM, they are self
explainitory from there.
