使用SAP JCO 3.0时是否需要调用BAPI_TRANSACTION_ROLLBACK？

Question

是否有必要调用BAPI_TRANSACTION_ROLLBACK或仅JCoContext.end（）会进行隐式回滚？

Answer 1

If the particular JCoContext.end() will end the stateful call sequence (which is not true for a nested context) then the respective underlying RFC connection will be reset. And this means that also an associated uncommitted LUW (Logical Unit of Work) will be canceled which results in an implicit rollback.

But if you know that a rollback is required then why not calling BAPI_TRANSACTION_ROLLBACK directly? I would prefer explicit operations instead of implicit assumptions. I guess this would make debugging and tracing easier as well.
