AHCS: Transaction Reversal - TO mapping across the environment

Content

We have enabled the Flexible Configuration of Accounting Hub through Feature Selection. We basically wanted to enable Transaction Reversal feature which apparently can't be enabled unless we enable Flexible Configuration feature. We also enabled Transaction Reversal at Manage Subledger Application task. Now the entire file structure has changed, as expected.

Now I in process of writing integration spec for Prod environment and I am not sure what would be the sequence of fields. Apparently whenever we configure the application in new environment the sequence of fields changed, please advise how to make sure the fields remain at same position when we configure a new environment (prod). or if we have any way of mapping like we have for supporting references.
