prevent a user from deleting a zero in sap analytics cloud planning

[Riri]

Hi all, how can I prevent a user from deleting a zero in sap analytics cloud planning template without data locks or locking the cell. The user should still be able to change the zero to any other value, except physically deleting the zero i.e. making it unbooked SAP Analytics Cloud SAP Analytics Cloud for planning

I do not think you can. You cant keep it open for change and also prevent from deletion. I am not sure of the use case but if you have used 0 to prefill valid planning combinations then combinations could be stored on a different intersection say version/audittrail and that combination should be locked/hidden. The table should have this version/auittrail along with main planning combination.
