Time dimensions in Planning Analytics Workspace
A time dimension defines the time periods that are used in your model. Most models use a
time dimension.
For example, here's a time dimension that spans multiple years and uses months as leaf members. Months consolidate to quarters, which consolidate to years.

A time dimension has the following member attributes:
- Last Period
- The final time period in the sequence.
- First Period
- The initial time period in the sequence relative to the current time.
- Previous Period
- The previous time period in the sequence.
- Next Period
- The next time period in the sequence.
- Short Name
- An alias. The short name is populated with the Member ID (the member name) - for example Jan 2018. You can modify the short name by typing in the cell.
- Long Name
- An alias. The long name is populated with the Member ID. You can modify the long name by typing in the cell.
To view the time attributes, open the time dimension in the dimension editor and click the Attributes tab.

You can add attributes, for example, you might want to add translations for the text. To find out more, see Create and edit member attributes in Planning Analytics Workspace.
