ACL Import Fails, No Error?

Today I was adding a new table to a scripted ACL project and kept getting an error.

This project automatically opens a folder on the LAN, reads the files in the folder, and loads all of them.

All I did was add one more file to the folder. ACL refused to load that one file.

Syntax error.

WTS?

Why You Must Validate Data

Before you analyze data, you must first validate it.

Otherwise, your analysis may not be accurate, and you may miss some important insights or errors.

This post is part of the Excel: Basic Data Analytic series.

Before analyzing your data, you need to check the following:

• Duplicate transactions do not exist.
• Required fields/key fields do not contain blanks, spaces, zeroes, unprintable characters, or other invalid data.
• Date fields contain real dates, and the range of dates is appropriate.
• Amount fields don’t contain inappropriate zero, positive, or negative amounts, and the range of values is appropriate.
• Each field is stored in the correct format. This prevents data from being converted on the fly into something else unexpectantly (e.g., user ID JUL15 becomes 15-Jul).

ACL Error: Not all Fields Imported via Script

Recently, I  ran an import script to import a delimited file into ACL, but the last 10 fields were not imported. And I didn’t know it right away, because I received no error message.

In addition (or should I say, in subtraction), the log did not indicate anything was wrong.

ACL Error: Cannot Export to Excel

Next time you get the cannot perform export to Excel error in ACL, try one of the 3 solutions described below.  The full text of the error is:

 Cannot perform the export.
You can export fields with maximum of 254 characters to Excel.

ACL: How to Create Your Own Scripts

Creating scripts (and editing them) is not as hard as many of you believe them to be.

Sure, it takes practice and time to learn the basics, but YOU can do it.

If you don’t learn scripting, you are NOT using ACL to it’s fullest, nor are you making the best use of your time.

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.

ACL tip: Create a File Import Script

Did you know that you can create a script to import a file into ACL? That you can automate loading a table?

I’m talking about the File > New > Table command in ACL, also known as the Data Definition Wizard. Yes, you can create such a script, and I’m going to teach you how!

The good news is that it’s so much easier than you think. The bad news is that it doesn’t APPEAR easy, but it really is, because ACL does the heavy lifting for you. I promise that if you hang in there, you’ll so be a pro. Just try it once, and you’ll be hooked!

ACL Error: Working Directory Does Not Have Write Access

On occasion, I have received the following ACL error: The working directory does not have write access permission (see below).

Simply said, it means: the working directory is not working; something is not write. :)

Seriously, the working directory is the directory in which the application wants to start, which is why it is also called the starting directory. This is the directory to which ACL expects you to save your ACL projects. That’s why ACL needs write access to that directory.

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: Quickly View/Print Table Layout

To quickly view or print the table layout in ACL, type dis in the ACL command line (dis is short for display).

The table layout contains information about the fields in a table, such as field names, field type (ASCII, Date, Numeric), field length, and most importantly, the expressions used to create computed fields. For more info on computed fields, see What is a Computed Field?

ACL: Strange Message in Log

If you’re an ACL user, I sure hope you read your ACL project logs and approach the JOIN command carefully. I recently received a good reminder. For an explanation of ACL, see this post.
