I'm working on a workflow development in which I have to invoke an external web service (non-SAP) from a workflow task. As soon as the work item is created in SAP, I need to send a notification via web service call. So I thought of having a workflow step to call the web Service.
(1) Can I use WF_EXTSRV wihout having a BSP application.? There is no BSP application in my case.
(2) What are the possible options I have to achieve this?
