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.
Additional information on Data Module Identifiers and their use can be found in the following IBM Cognos Analytics Community article.
