I was not able to find any answer on our client's question. "Actual Cost" field in Fin plan is not editable (which is of course correct), however "Actual Revenue" is editable which is very confusing for our customer...
As this field comes from virtual field "Amounts of periods" (naming from sandbox), it cannot be set editing separately by each field:
Note: When "Allow editing" is unchecked, nothing can be edited...But we need to edit at least Costs of course...
Does someone know how to achieve to have this field not editable?
Thanks a lot!
