The FAB UI provides the ability to leverage the TM1 sanboxing feature. To access this feature on a data entry grid:
1. Select Options, Show sanbox functions.
2. Click on Create a Sandbox.
3. Type in the sandbox name. Hint - pick a name that describes from which scenario, year, and account key or employee grouping you are creating the sandbox.
4. Note your new sanbox is created in the sanbox drop-down list. The Sandbox called "Base" has nothing to do with base funding. It is a TM1 name for the sandbox that the scenario uses.
