Regarding SAP integration

hi ,
can any one explain about difference between SAP integration in webmethods and SAP XI in SAP Netweaver…

which one is used in which scenarios…?
Thanks in advance…

Both are middlewares and will accomplish the same,webMethods uses (SAPAdapter) and SAP XI is focused on SAP integrations as well as other ERP’s using webservices communication.

which one is used in which scenarios…?
Well it depends on the company’s investment in middleware product they wanted to choose based on the Integration feasibility and robust ROI to get from it.

HTH,
