IDOC or RFC

[Former Member]

hi friends

i want to understand the advantages/limitation of idoc adapter vs rfc adapter. if i want to generate a customer or vendor in r/3 system, we can use respective IDOCs or BAPIs. but which is the best suitable in terms of performance, simplicity and flexibility.

Hi,

RFC's support synch processing but Idoc's support only asynch processing.

So, if your requirment is that you need to have a synch processing, then going for RFC's can help.But, if a standard Idoc is available and your requirment is asynch , then Idoc's should do the trick.

Ofcourse, if your SAP system is on a WAS of 6.20 or greater, and if load is going to be high, proxies provide the answer.

Hi Bala,

IDoc is convenient for aynschronous scenarios i.e you simply send a message and there is no response required / expected.

e.g. If you want to move vendor master data from one system to another, then IDoc is the best option.

However, there are other cases where you want immediate response to your request.

e.g. you want to create a Purchase Order, then after giving necessary data in the request, you need the Purchase Order No. back. This is synchronous scenario. For such scenario, RFC/BAPI is suitable.

In performance, IDoc is generally better than RFC. Whereas, RFC is more suitable where response is required.

As far as XI is concerned, the pro's and con's of sync and async scenarios also apply here. i.e. Async messages are always persisted, but sync messages are not persisted (unless loggin is switched on) etc.

Hi,

Refer this blog by Ravi on chossing the right adapter between RFC and idoc or proxy.
