Data Module Identifiers appended with underscore character

Troubleshooting


Problem

Why are some identifiers in Data Modules appended with an underscore character?

Resolving The Problem

In a Data Module an identifier is a string which is used to identify an object, either by itself or in conjunction with the identifiers of parent objects.  
The identifier string must be one continuous string and cannot contain spaces nor certain reserved characters or consist entirely of a reserved keyword.  Identifiers for reserved words are appended with an underscore.  The label of the object does not require an underscore be appended.
Example: Data Module created from a spreadsheet with a column named Date will be assigned the Date_ as an identifier, and how it is referenced in a Report Data Item.
