I have a customer portal web application developed in .Net from which I will be getting different values which are changes related to a particular sales order item in SAP. One among these values is the pricing formula used with the sales order item. I am using bapi_salesorder_change to update all the values other than the pricing formula. My input to the bapi is the formula id. I am not sure about the field which I have to use in the bapi structures to update the same. Also I don't even know whether I can use the same bapi to do the required task.
Requesting help ....
