Alias names make it easy to identify data within the Template Builder as you create templates for your merged documents. The alias name becomes the dataset name in Template Builder and the name you reference in your template when creating detail regions to merge report or query data.
Report and query aliases must be enclosed in brackets, cannot contain spaces or special characters, and must be between 3 and 20 characters long. They precede the id of the report or query in the URL (see below). The dataset names of Master, Org, User, and ReportData cannot be used as aliases because they are reserved for the default datasets.
