These commands allow you to set aliases or alternate names that can make reports easier to read and help your reader focus on the data values rather than the meanings of member (page, column, and row) names.
You can use aliases to display members in a report:
By alias alone. For example, display the name as Diet Cola rather than its corresponding member name 100-20.
As a combination of member name and alias. For example, display the name as Diet Cola 100-20.
In addition, these report commands also control the display of member names and aliases.
