Hi Radhey Mohan,
Your feedback already has the answer I guess. If I understood it correctly, you are using (or intend to use...) batch characteristic to capture classification status as "A" / "B" / "C". Is that Correct? If so, there is no harm is using this, as this is a compliant way by using batch characteristic to track special properties.
Form your initial requirement statement and then from the subsequent feedback, I am not clear what exactly you need to understand. Do you mean, you wish to update this batch characteristic as A/B/C during Result Recording (RR) or at Usage Decision (UD)? What exactly you are looking for? Do you already have any custom report to track this batch characteristic? What is your requirement? Please clarify!!
Thanks,
Arijit
