TimeTonic allows you to block the editing of certain rows in order to, for example, close the entry or modification of data over a given period or to lock your entries of estimates or invoices.
This works in the same way as a filter applied to a table or a view.
I want to make the data used to generate my invoices unmodifiable.
Click on the table options :
Then select : Manage read-only rows
Then select one or more conditions making your rows read-only.
It is considered here that the fact of having generated an invoice makes the line immutable. You will therefore no longer be able to modify the information used to generate it via the autodoc.
