Workflow | Get Metadata from Approver Who Signed off

The user who approves/completes the assignment is recorded into the built-in property "Marked as complete by" (ID 45) which is hidden from the metadata card. You can try adding this property to your notification template.

The built-in property has some limitations on how it can be used so if it doesn't work directly in your notification you can then try copying the information to your own property definition and then include this property in your notification. Example rule to copy the value with Compliance Kit's Managed Properties where "Assignment completed by" is a multi-select lookup property from the Users list:

We’ve set up an approval assignment where users can either complete or reject the task, but we are having trouble capturing the names of users who approve or reject these assignments.

After a user approves or rejects, we want to populate the "Approved by:" property on the document with the names of the relevant users. We tried the solution suggested in this topic, but unfortunately, we haven't had any success so far.

We also attempted using the relations "assignment.marked as completed by" and "assignment.marked as completed by," but with no results. Additionally, we tried implementing this solution through the Property Calculator and CK Managed Properties.

Could you please assist us in resolving this issue?

I have this question too.

It worked for me in a quick test with the configuration above. If you need help with your config please raise an Implementation Support Request.

Your quick test populates the property in the Class Assignment, not in the Class Document. But how to populate it in the document from assignments related with

Config details may vary depending on the vault configuration and requirements, so it's best to discuss this via an ISR case. The general approach should work regardless (copying users from the built-in property to another property).

:-(
For this case, having a simple example with a document and assignments would be nice.
