Current we dont have feature to add the reason code while scanning items for any stores this will lead to fraud in future.
In Ax we have an option reason code for counting journal.
We have an option for discounts/price overrides it can be recorded in transactions.

Repro steps:
1. Open MPOS
2. Select Stock Count
3. Choose NEW
4. Now it should ask for Reason Code to capture the reason
5. Data must be transmitted into D365
