Problem with BAPI , BAPI_SALESORDER_CREATEFROMDAT2

Hi

I have Problem i.e While Running the Bapi's BAPI_SALESORDER_CREATEFROMDAT2 , BAPI_TRANSACTION_COMMIT

for Creating the Salesorders. It is Creating the Sales Orders in VA02 transaction.

I have done like this...SE37 - >FM = BAPI_SALESORDER_CREATEFROMDAT2 and then Test - > Test Sequences -> BAPI_SALESORDER_CREATEFROMDAT2 ,BAPI_TRANSACTION_COMMIT

and In Test Directory i checked the Field Item = TVO.

But it is NOT UPdating the " Billing Plan " Dialog, what ever the Input has given.i.e I given Tables - > ORDER_ITEMS_IN -> Item = TVO.

Even though iam not getting filled up the " Billing Plan" Dialog.

Can i know what are all the Inputs given for these BAPI'S to get the "Billing Plan " Option in

VA02 Transaction.

Regards,
