Hi Mohammed,
Result field will come from the Out Come Name of any task.Each Task will have atleast one Out come name.For example if you look into Send Mail step as shown below it has one out come 'Mail sent' .
So the same will come in the log as "Result".If you want to get that outcome name do binding from your step "Are you sure there was no incident ?" to get _Workitem.workitemid into a container and pass this to WORKITEM_ID of FM SAP_WAPI_GET_WORKITEM_DETAIL .
Get the WORKITEM_RESULT field which will give you the Result as shown below.
