Accounting rule in the sales order not copied

Morning,

In the sales order form, i was used to copy the sales orders to credit it from there.

However, an user raised the point that the accounting rule did not get copied which generates an issue in AR because deferred revenue is not triggered because of this missing piece.

Would you know how to make the accounting rule copied when using the standard copy function?

Below the issue.

Credit memo -> No accounting rule

Invoice -> Accounting rule

Best regards
