I agree with your symbol note. It adjusts as you fill in the correct class.
The battery date implies installation date, this shows when you drop down, yes all part details come up if you click battery it opens even a picture can be added.
when you click on the last ppm, a full detailed list comes up.
note field, there you can add brand, supplier , etc. 2500 Characters and allows 20 pictures of parts used.
Each PPM ends up in the history, also alarms if you again replace same part again and have to click to approve, you can notes to that also if you wish to add a reason.
