Auditor Struggles, Part 4

This is Part 4 of a Case File series that describes how real auditors tried to apply questionable methods to auditing and data profiling. See Part 1, Part 2, Part 3.

Does the Process X team provide metrics around their process?” I asked.

“Yes,” the most senior auditor replied, showing me the web page where the Process X metrics were displayed.

After reviewing the page briefly, I said, “I see they do metrics by month. You have a year’s data; are you planning to understand how they prepare their metrics and re-calculate them to see if you get the same numbers?”

Auditor Struggles, Part 3

This is Part 3 of a Case File series that describes how real auditors tried to apply questionable methods to auditing and data profiling. See Part 1 and Part 2.

I looked at the third page of the handout and asked, “What is this?”

“A list of Active Directory (AD) groups and the user IDs in each group. I searched AD for any group containing the system name,” the junior auditor said, “and identified these 6 groups. I then downloaded all the members of these groups from AD into Excel.”

Auditor Struggles, Part 1

Some auditors struggle with basic auditing. So when these auditors try to data analysis, well you can imagines how that goes.

I recently met with a team of auditors to give them input on what data profiling would be appropriate to perform. And what analytics might be insightful.

This is Part 1 of a 4-part Case File series that describes how real auditors tried to apply questionable methods to auditing and data profiling. Do not try these methods at home or work. Don’t even dream about them, awake or asleep. 

How to Review Your ACL Log

Whether you script your projects or use menu commands, you need to review your ACL log carefully.

Good analysts review their results and the log as they work in ACL, after they think they are done, and have others review their log before the ACL project is relied upon.

(You can’t imagine the dumb mistakes my team and I found that saved us a lot of embarrassment later.)

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 Add Computed Fields via Script

Once you’ve mastered creating computed fields, you’re ready to add computed fields to a table via script. It is easier than it sounds.

If you need some background on computed fields, see my previous posts, What is a Computed Field? and How to Add a Computed Field (manually). Now let’s explore writing a script that adds computed fields to a table.

ACL: Edit Scripts Easily

As soon as you create an ACL script, you often have to add to it or edit it. There’s an easy way to do it.

Optimize ACL Scripts

Have you been following the “Optimizing Script Performance” series on the ACL Blog? aclkevin has been offering some great tips.

In case you missed them:

ACL: Add a Custom View to a Table

Adding a custom view to an ACL table comes in handy when you want to 1) change the order of the fields in an ACL table, or 2) view a select number of fields.

You can add a custom view manually or via script. We’ll tackle the script version first.

This post is in response to Les’ question about reordering fields in a table.

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 tip: Rerun a Join Easily

Rerunning an ACL join command is much easier than most people realize.  And everyone using ACL screws up joining two tables more often than he’ll admit.

It goes like this: You painfully select the primary keys, the secondary keys, the primary fields, and the secondary fields, enter the output table name, and run the join. The join ran successfully, but you forgot to add one primary field or to adjust the options on the More tab. Now you have to do it all again. Or do you?
