DS for a drill form?

I think you'd have to use the getattach cgi call to return back all of the comments (attachments), assign them to an array and then search the array to find the ones that match your search.

But even before that - can DS be used to replace that attachment form?

I have used a text box to capture comments and then write attach to save them.

I don't think I'm presenting my question properly. I'm not asking HOW to do the attachments and/or anything related to the design of what I'm doing - what I can't find is within design studio what specific form do I even work with to modify? Its not AP20.1 - its the "attachment" drill from the invoice field.

I'm not sure if any drill forms can be referenced from UI...does this make sense?

I know my plan B is to come up with my own form that I call from Attachments instead, but I was trying to avoid that since what I want to do on the attachment screen is very simple

Why can't you just add a text box on AP20 instead of opening Lawson's subform. You can't get to the drill around forms with Design Studio to modify them (as far as I've seen).

The short answer is no, you can't use Design Studio to alter the attachment screen.  This is a global function/window housed in the HTML/Javascript structure in your WEBDIR.

To customize it, you would have to modify those files.  However, unless you somehow specified that certain features show for specific screens, they would be global changes.

Hope this helps,
