When an account move is duplicated, the related analytical lines are also duplicated. The new account move is created in draft state and the analytical lines are created in valid state.
If the amount of the account move is changed, Tryton prevents the posting because the relationship with the analytical line is incorrect.
However, if only the date is changed, the accounting entry can be posted creating a discrepancy between the date of the account move and the date of the analytical line.
Is this behavior correct?
I think that this behavior can lead to errors and that we should add some control over the modification of dates.
