I have developed a Wf in which i there is one mail step to send a notification to initiator of the WF.but req is this mail should go to initiator's Extrenal mail id not to Sap inbox.
Using FM HR_FBN_GET_USER_EMAIL_ADDRESS i am fetching the email id of that person.
how to send this mail to this external ID?What are the configration required?
if you had searched 'external mail' in this forum, you would have got lost of threads which could answer your query.
Nevertheless, for external mail, since you have fetched the email id of the user, pre-requisites are:
SCOT, SMTP > INT (node) settings which you need to tell the BASIS, where a report RSCONN01 is run in the background.
Once this is done, you have either options of sending it using a FM SO_NEW_DOCUMENT_SEND_API1 (which you could use in a BORmethod, where this method is put in task of your WF) or directly use SendMail step where you can put the email address that you fetched from your FM.
