How to check if payment terms have been overridden in order management

We’ve identified several sales orders where the payment terms differ from those defined in the customer master file. We suspect that the payment terms may have been manually overridden during order entry or processing.
Request: Could you please confirm whether there is any system log or audit trail that tracks changes or overrides to payment terms within the Order Management module? Specifically, we are looking to understand:

If such overrides are logged. Where these logs can be accessed. Who performed the override and when.
