Correcting a completed chart
A finished chart is a record, not a draft. How to put something right without quietly rewriting history.

Someone charted 30 vol and it was 20. It's a small thing until the next colour service is planned off it, at which point it's the only thing.

Completed means completed
Once a chart is completed it's read-only. The fields render as what was recorded, blanks say Not recorded, and there's nothing to type into. That's deliberate: a chart is a record of what was done to a person, and a record you can quietly overwrite isn't one.
Putting something right is a correction — the original is kept, your change is applied, and both the change and your reason go into the chart's own log.
Making a correction
- 1
Open the completed chart and press Correct, top right. A panel opens beside it.
- 2
Write the reason first. It's required, and it's the part somebody will actually read later — "wrong developer volume typed at capture" tells them something; "fix" doesn't.
- 3
Change the fields that are wrong. Leave everything else alone — only the fields whose value actually changed are recorded, so the log stays a list of real edits.
- 4
Press Save correction.
The chart stays completed throughout. It doesn't reopen, it doesn't go back to in progress, and its capture date doesn't move — the visit still happened when it happened.
What a correction can't do
It can't clear a field. If a field has a value and you empty it, you'll be told rather than have the edit disappear — a correction sets values, it doesn't remove them. Where something genuinely shouldn't have been recorded, write that in words instead.
It also can't be used on an in-progress chart, because there's nothing to correct: an open chart is still being written, and Save progress is the whole mechanism.
Reading the log
The Corrections panel at the bottom of a completed chart lists every correction made to it, newest first, with the reason and the date. A chart with no corrections says so.
That list is worth glancing at before you rely on a chart. A record corrected once is a record somebody was paying attention to. A record corrected four times in a week is a template question — usually a field whose label doesn't say what it wants, being answered four different ways.
Common questions
Why can't I just edit it?
Because it's a record of what was done to somebody. A record you can silently edit is a record nobody can rely on, including you — six months later there's no way to tell what it said at the time.
Where's the Correct button?
Top right of a completed chart. It isn't there on one that's still in progress — that one you just edit and save.
Is a reason really required?
Yes. The reason is the whole value of the correction; without it the log records that something changed and nothing about why.
I need to empty a field I filled in by mistake.
Correcting can change a value but not clear one — you'll be told so rather than have the edit silently ignored. Put the accurate value in, or write what the field should say — "recorded in error" — in words.
Does the correction show who made it?
The correction is recorded against the person who made it. What the Corrections panel displays is the reason and the date — the list is a record that something was changed and why, not a full diff.
Can I correct a correction?
Yes, as many times as you need. Each one is added to the list; none of them replaces an earlier one.
