I have a workflow that needs to call in an approval subflow, but I'm unsure how to set up the outputs. The subflow input uses a reference field and calls up the catalog service request that needs to get approval, but what would my outputs look like? I watched a couple of videos and it looks like the approval state is usually set up as a string so I set up "approved" and "rejected" and then assigned subflow outputs based on that (see the pictures for reference). The error that the regular flow throw up when it gets to this subflow references a "null" value. Maybe I need to set up outputs for all the approval state choices? Or maybe it should be a choice type rather than string and reference the approval table? Can someone help me figure out how to get this set up correctly so that the approval subflow correctly passes the approval to the main flow? Thanks!
Hi Tara,
I can't tell from your screenshots and description if this is a workflow that you created in the Workflow Editor, or a flow that uses Flow Designer. Here is an example in workflow.
The sub-flow is called in a Workflow Instance activity which is created by dragging the sub-flow name from the Workflows list onto the canvas. This activity notes the name of the workflow (sub-flow) to execute, and a return value that can be mapped to a scratchpad variable
In the sub-flow, you have a Return Value activity for approved, and one for rejected on paths that come from the Approval activity Approved and Rejected conditions.
Then back on the main workflow, the Workflow Instance activity leads to an If activity to determine if the return value is approved or rejected
answer = ifScript();
function ifScript() {
if (workflow.scratchpad.approval_result == 'approved') {
return 'yes';
}
return 'no';
}
