ACL: How to Add a Conditional Computed Field

In ACL, a conditional computed field (CCF), is basically a regular computed field with some fireworks.

It looks and acts much like a regular computed field, but has some extra parts that do some extra work. Fortunately, the extras are NOT complicated, and after reading this post, you will find that will you use CCFs frequently.

So what’s the difference?

Compare Multiple Fields with Excel vlookup (Easy)

When you need to determine whether several fields in 2 Excel documents (or tabs) match, all you need to do is combine the fields in each document into one value and then compare the 2 values using vlookup.

You could do this many ways, but if you’re new to Excel formulas, I think this way is easier to configure and understand. I’m assuming you’re familar with the basics of Excel and vlookup already.

If you are not familiar with vlookup, you might want to review this first, as my post does not teach you vlookup, just another way to use it.

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.

Error: ACL Desktop cannot complete this function

When you’re trying to load a new file into an ACL table, you’ll sometimes get this error:: “Application error. ACL Desktop cannot complete this function…contact ACL Technical Support…” (see below).

Here’s the situations in which I’ve encountered this error, and how I’ve fixed it (most common and easiest to fix situations are first).

Master List of ACL Articles and Tips

To make these posts easier to find (and link to), here’s a list of all the ACL posts on this blog in alphabetical order, and by most popular.
I’ll add other posts as they are written.

ACL tip: What is a Computed Field?

A computed field is a field in an ACL table that you create using expressions.

An ACL expression is similar to a Microsoft Excel formula [e.g., =SUM(A1:A2)] in that it contains at least one function [like SUM]. Excel formulas operate on cells (like A1 and A2), but computed fields operate on fields.
