RFC/IDOC ADAPTERS

[Former Member]

Hi,

could any one plz differentiate the major differences between RFC adapter and Idoc adapter and the two different scenarios where they are used as iam new to XI.

Hi Raj,

you use IDOC adapter only if you want to send idoc to R/3 from XI + there's not sender IDOC adapter

more on idoc adapter:

you user RFC adapter if you want to send or receive RFC calls (invoke RFC FM )

Hi Raj,

Idoc:

-idocs are async in nature

-adapter resides on the abap engine....hence not listed

in the ID

-uses r/3 connection while defining rfc destination

-very good performance

Rfc:

-rfcs are sync in nature......response can be mapped

-resides on the j2ee engine

-uses tcp/ip connection for rfc destination

-worse performance than IDoc

Scenarios:

for sync scenarios you opt for RFC, but they cant handle mass data transfer.

Hi

go thru these blogs for RFC and IDOC

For RFC

/people/arpit.seth/blog/2005/06/27/rfc-scenario-using-bpm--starter-kit

For IDOC

/people/prateek.shah/blog/2005/06/08/introduction-to-idoc-xi-file-scenario-and-complete-walk-through-for-starters

Hope it helps.

Hi Raj,

IDocs r every time asynchronous (without a response). This has some advantages (perfomance) as well as handicaps (error handling). IDocs r SAP standard communication with very good monitoring.

For own development it s easier 2 take RFC. Main advantage: synchronous messages r supported. The whole technique is not so difficult, but worse performance.

For R/3 systems >= 6.20 u can choose abap-proxys for communication as well.
