OK cool so there is a linkage between the three, a parent sc_request.
In terms of fulfillment, is there a particular order these must follow: request item 1 before request item 2 before request item 3? If so you may need to have different WF Event names so each can wait for a specific step. So if request item 1 has to be completed before request item 2, then in request item 2's workflow you can have a WF Event waiting for "reqitem1_complete" and then in request item 3's workflow you can have a WF Event waiting for "reqitem2_complete" as an example.
So with this said the following code should work for you:
// Get all request items linked to parent request
var reqItem = new GlideRecord("sc_req_item");
reqItem.addQuery("request", current.request);
//Exclude current request item from query
reqItem.addQuery("sys_id", "!=", current.sys_id);
reqItem.query();
while (reqItem.next()) {
// Get running workflows for the current request item
var wf = new Workflow().getRunningFlows(reqItem);
while(wf.next()) {
new Workflow().broadcastEvent(wf.sys_id, "ENTER YOUR EVENT NAME HERE");
}
}
