to use BAPI_SALESORDER_CREATEFROMDATA2 or BAPISDORDER_GETDETAILEDLIST ?

Hi All,

My company have this business scenerio, the sales order is flow from the e-store (website) to a legacy system. The volume is quite large, I need to pull this sales order in real time to SAP system. I plan to use BAPI. Shall I use BAPI_SALESORDER_CREATEFROMDATA2 or BAPISDORDER_GETDETAILEDLIST ? Is BAPISDORDER_GETDETAILEDLIST used for mass creation ? For example, I pull all these sales order (2000 record) to a internal table, how to process in this BAPI, is a loop needed? I don't know what data shld contained in I_BAPI_VIEW to import ?.

Thanks in advanced.

Regards,

Janice
