Email & Workflow

[Dimitri Dupont]

Dear all,
I use a workflow to validate requests and to send a confirmation of a approval/refusal of those requests. When sending an email from the workflow, SAP always use WF-Batch that is common to FI/HR/... As it is common, the SAP BC team refuses that we use that user as sender. So 2 possibilities : 
1- Adapt the existing task specifying the sender 
2- Use an external function/report to send those information 
Possibility 1 would be the best one ! 
Does anybody have implement one of those things ? Any help ?
Thanks a lot in advance 
Dimitri
