This item has been identified as an outstanding known issue as of the March 10, 2018 platform release; a workaround is provided until the issue is officially fixed.
If a line item is formatted as a percentage, entering 0 as a value results in the following error:
You can still copy and paste a value of 0 into that line item and it will work (either from another Anaplan Cell, or an external application) or delete the value, which will make it 0.
This does not seem to affect imports.
Delete the value you would like to be zero, making it zero.
