Bulk insert into Oracel EBS

 </ns0:PO>

header details is storing one table and line items storing in another table through procedure

One way is i will split the files (1 header ,1 line item ) sending to oracle buts its causes performance issue if i have 10 line items it will hit the procedure 1o times 

second way is performing composite operation  buts its directly bulk inserting data into tablesits not recommend approach for our requirement

my question is any another way is bulk inset through procedure ?

I have followed one approach

Procedure have xml type parameter and BizTalk sends xml file as a parameter procedure takes file do business logic and its insert into database and worked  .
