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.)
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).
Here’s a list of my basic data analytic procedures for Excel.
As I add more posts to the series, I’ll update this list.
I created this series because:
1) I often get asked by new AND EXPERIENCED auditors how to do these tasks,
2) when I review workpapers, I realize too many auditors are not aware of these functions,
