You can create your own names for generations and levels in an outline. The name is a word or phrase that describes the generation or level. For example, you might create a generation name called Cities for all cities in the outline. You can define only one name for each generation or level. Once defined, you can view generation and level names in the Properties tab in Outline Viewer.
Use generation and level names in calculation scripts and report scripts wherever you need to specify either a list of member names or a list of generation or level numbers. For example, you can limit a calculation in a calculation script to the members of a specific generation.
In a dimension that allows duplicate member names, you can specify that unique member names are required for a particular generation or level.
To create, modify, or delete a generation name or level name:
Perform an action:
Select Outline, then Generations to open the Define Generations dialog box.
Select Outline, then Levels to open the Define Levels dialog box.
From the Dimensions list box, select the appropriate dimension name.
To create a generation or level name, complete the following actions:
In the Generation Name or Level Name column, click the cell that contains the text, <Click here to create a new generation> or <Click here to create a new level>.
In the text box, enter the generation name or the level name, following the same naming rules as for members.
In the Number drop-down list box in the same row, select the generation number or level number. For example, to name a generation for the months in the Sample Basic database, select 3. To name a level for the months in the Sample Basic database, select 1.
Optional: In outlines that allow duplicate member names, if you want to require unique member names within a particular generation or level in a duplicate member name dimension, select the check box in the Unique column.
If you want to delete an existing generation name or level name, click Delete next to the generation name or level name to be deleted.
If you want to keep the dialog box open, but undo all changes made in the dialog box since it was opened, click Revert.
Click OK.
