ACL: How to Add a Computed Field

If you’ve been wondering how to add a computed field to an existing ACL table, you’re at the right place. I’ll take you through it step-by-step.

In ACL tip: What is a Computed Field?, I defined computed fields and provided 2 examples. I suggest you read that post before you dive into this one.

That post also explains expressions and functions, which you need to understand when creating computed fields. Both that post and this one are long ones, complete with graphics. You might want to print them both out first…

In this post, I’ll show you how to add the c_Region field that is described in the computed field post. It’s not as hard as it looks.

For me, it always happens when I open the Edit Layout dialog box to create a computed field. Never any other window.

Or in ACL terms, also known as “What happened to the Edit Layout screen?”

Note to non-ACL users: This problem isn’t particular to ACL, so you might want to read the “Finding the Cause” topic below before you blow off this post entirely.

I’ve noticed that this only occurs after I last used ACL on a 2-monitor system. The setup I normally use is my laptop screen plus an additional monitor.  But when I’m at home or on the road and only have my laptop, fire up ACL, and go to Edit, Layout, the problem occurs: apparent ACL freeze with every other application working.
