Undo has the following constraints:
- You cannot use Undo on a recently refreshed module. Anaplan holds the three most recently viewed modules in memory. If you work through four or more open modules, for instance from module A to D, Anaplan refreshes the data in the oldest module, which in this case is A.
- If two users enter data into the same cell in a grid sequentially, the first user cannot undo their data change as their grid doesn't display the most recent data value.
- If you make a change to a cell and then use a filter, or pivot the module view, you cannot use Undo.
- You cannot use Undo if a large import or complex formula is being processed. You can use Undo when the process is complete.
- If you use Undo on a cell in a line item that is a numbered list, the undo message displays the unique identifier for the item, not the display name.
- Undo can only revert values when there's a one-to-one relationship between the unique identifier and the display name, in a numbered list. If the same display name value appears more than once in the numbered list, Undo cannot identify the value it should revert to. If you use Undo on a duplicate display name value, it returns a blank value to the cell because the replacement value is not unique in the list of display names.
- If you use Undo after amending a Breakback total, the cell reverts to the previous value and Breakback is recalculated.
- If you apply Breakback and then edit one of the distributed Breakback values before you use Undo, the edited value reverts, not the Breakback total value.
