WORKFLOW : Task marked as a background to send a mail to ext id not working
I have configured a workflow by creating a subobject of BUS2012 and in my workflow i have created one activity which will send a information mail to approvers of Purchase order on a external mail id.
I have set the task to be processed in background mode it means this will be processed by WF-Batch user, when i see it in workflow log all the activities are getting processed successfully but im unable to see any mails flowing in SOST tcode.
When i perform this activity in Foreground mode and assign a external agent to a workflow task everything is working pretty fine and i can see the mail outflow in SOST tcode too but the same is not working in background processing mode.
please let me know is there any setting which needs to be checked out?
Awaiting for your positive reply on this!
