Table Registration shows limitation error

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

When I was registering 15 Oracle tables in DataMaker, we got the below warning :
"Be aware that you are limited to 2000 characters when building expressions for tables with more than 57 columns"

Is this something to be concerned about? Was there a problem?
Or is this just a standard warning?

Environment

TDM 
Test Data Manager
Datamaker

Resolution

This is just a warning.
It says that if a table contains more than a set number of columns, you will be limited to 2000 characters when creating data definition expressions.
This is a standard limitation. 
You can still see the tables are registered without any issues.
