Different Bill to Customer

Hi Team,

As process I tried to create the Sales order from the Charges option, and against the each charge line I selected different BILL to customer (with same SHIP TO customer for all lines ) and was expecting that I will see the different Sales order number once Lines Submit. I submit all the charges lines simultaneously however found that only 2 different sales order gets created, one against the customer selected at the SR level and another with other BILL TO selected at the charges level and the second Sales order is same for all the remaining charges lines.

Please advice if I missed any setup or any profile needs to be setup for this. We have a requirement for the business that they need to raise invoice for different BILL TO customer against the sa,me SR. For e.g. one for Insurance co, credit customer, cash customer, etc. I have attached the document for your references
