Hi, I have a layout with a portal and need to know when and who was the last one to update any of the fields of the layout - including those in the portal.

I'm using a technique that consists on creating a third relationship (self-join with the child table) and a calculation based on it (please have a loot at the attached file, yellow highlighted field in 1st layout). This seems to work but I would appreciate some feedback or suggestions in case there is some other techinque that is more recommendable. Many thanks!

Why not simply:

Max ( Modified ; Max ( Child::Modified ) )

Then you don't need the extra relationship.

Thank you for having a look at this. I created the extra relationship so I can also keep track of the last name (or account) that modified either the parent or a child record, that's why the extra relationship is sorted by mod_timestamp. I have updated the file (attached - please see highlighted fields) ... actually, the extra relationship should be with the parent, not a self-join.

I wonder if this is a correct way of doing this ... thanks again!

If you need the name as well, then I suppose the extra relationship can be useful. It could be slightly simplified, though.

It's not only simpler, but it also evaluates faster. Thank you comment.
