You use the Define Generations dialog box to create, edit, and delete generation names.
You can use a generation name in calculation and report scripts to refer to all members to which the generation name applies. For example, the generation name “Month” refers to all month members (Jan, Feb, and so on).
You can specify only one name per generation. The specified name must be unique; that is, it cannot duplicate a generation, level, or member name or an alias or conventional alias. You must follow member naming rules. See the Oracle Essbase Database Administrator's Guide.
In the Dimensions box of the Define Generations dialog box, you select the dimension that contains the generation to which you want to assign a name.
In the following columns, you view information and perform actions:
State—Displays New or Modified, respectively, for generation names that were created or updated after the dialog box was opened. If no names have been created or updated since the dialog box was opened, nothing is displayed.
Number—Displays the generation numbers of existing generations. If you are creating a generation name, in the column, click the first empty cell, and assign the next generation number. If you are changing a generation number, click the cell to be changed, and select a number. You cannot change numbers that are associated with DTS members.
Unique—For duplicate member name outlines, for dimensions that can contain member names, select a Unique-column option to require unique member names within the associated generation.
Generation Name—Displays the names of existing generations. To create a generation name, in the column, click the first empty cell, and enter a name. To rename a generation, click the cell to be changed, and enter a name. You must follow member naming rules. See the Oracle Essbase Database Administrator's Guide. You cannot rename generations that are associated with DTS members.
Delete—Select a Delete-column option to delete the associated generation name.
