For first sales order I didn't get any error. But when I tried to create another sales in same session I am getting this error for when BAPI_TRANSACTION_COMMIT is executed. When I check in ST22 got the below error analysis.
While debugging, I got to know that, in internal table DA_XVBFAI has first created sales order data and new sales order data. So it is getting dump. I went through so many pages but didn't the answer, Please hep.
