Hi all, I am going to show a popup message (like warning or alert) inside a workflow action script. The workflow action script is executed by clicking a button which is created inside a workflow. I placed 'N/ui/message' code inside the workflow action script, but it doesn't seem to work. How can we do this?

Go through Workflow Triggers so you can recognize where custom actions run

This is not same case. The problem is the popup should be inside Workflow action Script.

is your custom action a server trigger or a client trigger

The custom action calls workflow actions script.

you will want to understand where your script is running , on the server or on the client

The script copies current Sales Order, so we can say it is running on server.

it running on the server, but literally because custom actions only have server triggers

Yeah, I know it. So I posted the problem in the suitescript channel.

there are different options available to you depending on the trigger

Let me explain in detail. SO form has a custom button and when click the button, it copies the SO to create a new SO. At this time, if any item lines are not copied (by a condition), I have to show a popup.

use either Form.addPageInitMessage, Form.clientScriptModulePath or the Show Message Action

There is a line column (checkbox) in item sublist of SO. Can we check if all items are not checked in the column in workflow?

workflow conditions generally dont work with sublists

Suppose the workflow action script set a relevant field. But how to let the workflow know it should show popup?

use a condition on the show message action

but the problem is show message action should work when button is clicked

not an option, the button only triggers a transition

I am not sure if it works yet. Anyway thanks for your time for this.
