Hi Ashok,

see if your SAP WEB AS system is having 6.2 or higer version, then the best way is to go for proxy - use XI adapter in ID then and connect SAP R/3 to XI with a HTTP conn made in SM59 in XI.

If you dont have WEB AS 6.2 or higher, then make a RFC adapter comm channel for connecting to R/3 from XI by making a R/3 conn from XI to R/3.

But if you have to get data from SAP and you have an IDOC for it, then the best way is to make an IDOC adapter in XI. If you dont have any IDOC available in SAP for getting your data, then go for proxy or RFC as i have said above.

Hope this solves your query.

Thanks,

hi

if u r WAS<=6.2 U Will use IDOC or RFC.

If it is async and SAP System use IDOC

If it is sync and SAP System use RFC.

if u r WAS>=6.2 Use proxy.

One of the things that SAP strongly suggests is the usage of PROXIES.

The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.

for clear idea go through

proxies provide a better perfromance than other adapters and so, if you are planning to integrate with a SAP system that is on a WAS >= 6.20 then use proxies.

If lesser than 6.2 then for asynch proxessing using idoc's and synch processing using RFC's.

Proxies support both synch and asynch calls.
