Within every Cube, there is a Top Level Dimension (TLD) for Time, where all your data's date ranges will be located.
For example, if you choose to have your Cube time dimensions set up by month, you will see your full date range sorted by months within this tab.
Within the Time dimension, there is the option for users to add their 'Cube Opening Balance' or an individual year.
Setup during your implementation period; once set in Cube, time dimensions cannot be edited directly.
Custom Time Dimensions
If you would prefer custom time dimensions such as daily, weekly, bi-weekly, 4-4-5, or custom month-end dates, but your Cube is already setup, please contact your CSM or reach us at custsuccess@cubesoftware.com for discussion / potential next steps.
