TimeTonic allows you to block the edition of certain lines in order to, for example, close the data entry or modification of a given period or to lock your entries for quotes or invoices. This works the same way as a filter applied to a table or a view.
I would like to make no editable the data used to generate my invoices.
Click on the parameters of the table.
Then select: "Manage read-only rows".
Then select one or more conditions that make your lines read-only.
It is considered here that the fact of having generated an invoice makes the line immutable. Therefore, you will not be able to modify the information used to generate it via the autodoc.
