XI vs Idocs system

[Former Member]

hi

i use a software on OS400 who do some data transfert with SAP R3 versions 3 or 4 (4.6C for example). We receive and sent IDocs with RFC protocole.

How works XI, what the difference with old IDocs system. how do new data transfert between SAP and OS software with XI ??

thanks a lot, i'm a noob in this )))

Hi,

To connect to SAP R3 using XI there are two ways through RFC or IDOC.

When data is sent from RFC or as a IDOC to XI,then XI converts that RFC message to XML format and then forwards it to receiver system(whether SAP or Non SAP)

Similarly in case of IDOC XI converts that IDOC to IDOC XML using R3 IDOC Metadata and then forwards the same to receiver system whether SAP or Non SAP.

To transfer data from or to XI again we need RFC destinations to be created on Server side or R3 side.

Thanks.

There is no difference in your case as your SAP WAS <6.20.You have to use RFC or idoc.But the usage of XI gives you various monitoing ,error handling mechansisms and connection handouts in XI and integration knwoledge resides in one system and does save the application system time from doing the EAI things.

Hi,

You can use either RFC's or the Idocs with XI to integrate with SAP systems .
