What are the ways to implement "UNDO" action/process with a help of a custom created button on dashboard in Anaplan? This UNDO button would reset values of cells to it's original initial value.
I would copy the module you want to reset, remove any calculation line items, set the data to what you want as the reset point. Then create a module to module import from this new module to the original...
For the module for which you want to create an undo action, create a copy, keep this copy on the dashboard for any interaction by the user. Give users, two buttons each containing a model to model import, one from copy to original and the other from original to copy. Once the user is done making changes, they will need to press a button saying 'Confirm Changes' that will take the data from copy to original. Another button called 'Reset' would bring the data from Original Module to copy module.
Hope this helps,
Thanks and Regards,
