Issues with loading the Invoicing and Accounting rule in the Sales order FBDI file

Hi Team,

We have a requirement to load the invoicing and accounting rule data in the Sales order conversion and we have defined the cross reference for both rules through cross reference FBDI. I had loaded the Sales order data with the rules but both the rules were not updated after the Sales order is getting imported.

If we define the accounting and invoicing rule in the item specification then automatically the rules are derived in the Sales order without passing the data in the SO FBDI file. We need to have the requirement of the rules getting loaded with the sales orders without defining it in the item specifications. Requesting for any suggestions on how to overcome this issue and load the Sales orders with the rules. Thanks in advance.
