You’ve got data containing fields that reference each other?
Users often object: “But we’ve got fixed reference lists.” But they are not always available or they are based on legacy data that got into your system during a migration project some time ago.
One simple example of this is the ZIP code. Every city has a ZIP code. Can you find this city in your data? Or is there a name variant, an abbreviation or maybe even an incorrect city in your address master files?
Have you entered a customs tariff number? Is it still up-to-date? Compare it to the official list and find out if your data are still up-to-date.
These are just some examples. Of course, our consultants can also help you with other cases.
