Just ran accross an interesting feature in FM7.
Assume you have a priviledge set that allows view only access to
certain layouts.
When a user is logged in with that access and a script not running with
full access sets a field while at this layout, it works.
If however, that same script tries to create a new record, it does not
work.

In article <1124684463.337016.40450 (AT) g44g2000cwa (DOT) googlegroups.com>,
a (AT) pottnerconsulting (DOT) ca says...
"setfield" iirc, is one of the fiew scritpt steps not bound by "layout
rules"; it directly updates the field, without interacting with a layout
object. (ie it doesn't need the field in question to be on the layout.

Contrast to "insert calculated result" which does.

That I didn't know. I'm not overly surprised though.
