Detect When Attachment is Added - Field Maps Tasks

CodyPatterson — Thu, 04 Dec 2025 19:47:07 GMT

Hey all,

Enterprise 12.0

We're looking into Field Maps Tasks, and we want a way to prevent final submission until an attachment is added, any ideas?

Currently a way that we're trying to detect in the moment if an attachment has been added to the actual item in Field Maps is the way below, is this possible?

if (count(Attachments($feature)) != 0) { return "Passed" }

This is just a demo text to verify if this would work, it adds the "Passed" value after it is submitted, but the value is not calculated until actual execution, I have seen other attributes like this in the past, but was curious if you all have had any ideas?

Hi @CodyPatterson,

It is possible to do so. The way to go about it is to add a constraint rule on the attachment table itself to look for the globalid of the related feature record and then set the insert trigger to have it look to see if the required attributes have been filled out.

Hey @RPGIS

Thank you for the response! I'm currently blanking on where to find this constraint rule placement for the attribute table, I forgot to add it initially but this is Enterprise 12.0 if that helps the locating of this!

That actually makes it the easiest since the latest version of Enterprise actually allows for better control using attribute rules. So to get to the rules themselves:

You can either right click on the table/feature in the catalog and select Data Design or similar to the image below
From there you can click on the attribute rules
Click on the constraint tab and you can then add your rule.
