I have received below message from Authorize.net team:
Transaction and Batch ID Reminder
In the coming weeks, due to system updates, it will be possible to receive Authorize.Net IDs (Transaction ID, Batch ID, etc.) that are not in sequential order.
For example, currently, if you receive a Transaction ID of "1000," you could expect that the next Transaction ID would not be less than 1000. However, after the updates, it will be possible to receive a Transaction ID less than the one previously received.
If your system has any functionality that expects Authorize.Net-generated IDs to be sequential, please update it immediately so that you will not see any disruptions.
Additionally, please make sure that your solution does not restrict any Authorize.Net ID field to 10 characters. If you are required to define a character limit when storing any of our IDs, the limit should be no less than 20 characters.
What does this message mean? and should I do some configuration changes on the admin side as well?
