You can now create budget versions in Planning. This will allow you to create versions of an existing budget and edit budget versions.
Using Budget Versions requires the use of Boolean 1 and Tag 5 in the Budget App dimension fields in Planning Setup. If you previously configured these fields, you need to delete them before using Budget Versions.
