Open a Call from Forms → Submissions. The header shows the outlet, who captured it, when, and its status. The answers sit in a panel for each page of the form, with names in place of codes (an outlet's name, a product's name) and any repeater rows in a table.
Where you are allowed to, each answer has a Correct button. Enter the
new value, a cause code (why it was wrong, for example
data_entry_error) and a note, then apply it.
An upheld query creates its correction for you.
