Unable to override the accounting rule as per the 'Transaction Origin Type' in the DELIVER TO EXPENS

Hello All,

We have a requirement where we need to override one of the segment rule as per the 'Transaction Origin Type'. This particular account type which we require to consider is as follows:

1. Transfer Order Deliver to Expense

2. Transfer Order Expense Return to Receiving

We have created a complete accounting rule for the above accounting type, for the further reference please find the below screenshot

Mapping Set:

Now, as a part of the requirement we need to override the Natural account segment as per the "Transaction Origin Type" which we are not able to find the logic for the same.
