Opening KM updates are not visible after saving on the Form 888 (Tyre Data) because of the way the form’s update functionality is designed. In this form, if any field or value related to a tyre (such as Opening KM) needs to be updated, the update must be done by searching through the tyre number and not the vehicle.

Currently, when the user searches using the vehicle number, the form only displays tyre details linked to that vehicle but does not allow updates to the tyre’s master data. Therefore, updates made this way are not reflected.
To properly update the Opening KM or any tyre-related data, search and update using the Tyre Search option at the top of the form.
