Modifying or cancelling data and actions taken

Processes by which a user can modify the data they have entered, have their entry cancelled or have actions resulting from their entry cancelled, for example cancelling an order or a bank transfer.

Note: The screen containing a form which modifies or deletes data, or which transmits answers to a test or examination, or whose validation has financial or legal consequences, must explicitly indicate the period during which the user can request the cancellation of their input. It must also contain the procedure for cancelling the entry. This process does not have to be available online, although it is recommended.
