Surendra,

<b>What is the RFC and IDOC Adapters in XI</b> :

<b>IDOC:</b> Generaly standard IDOCs are used to update the data in R/3 or to extarct the data from R/3.

<b>RFC:</b> Are generally used for synchronoue scenarios.

<b>in which scenarios we use this adapter</b>

For example you can use the IDOC <b>ORDERS05</b> to post the sales orders.

Similarly you can use <b>BAPI_COMPANY_GETDETAILS</b> to fetch the company details.

<b>what is the advantages and disadvantages of RFC , IDOC ?</b>

<b>Advantages:</b> Both can be used for data retrival and posting. RFC can be used for synchronus purpose but IDOCs are always asynchronous.

<b>Disadvangages:</b> If you are using custome made RFC/IDOC then you have to import the RFC/IDOC into XI every time when you make any small changes in the structure.

Also go through this blog to choose the right adapter to integrate with SAP systems.

Hi Surendra,

Whenever XI communicates with any SAP system ...it can communicate by

1)RFC

2)IDoc and

3)Proxy

u can use Proxies only if the WAS version is >= 6.20.

see this blog....u can find evrything u want....

"<b>read the blog top to bottom to understand the advantage of using Proxy over Idoc and RFC</b>"

hi Surendra

IDoc Adapter:

IDoc adapters are required when the receiving system requires the data in a structural format, which can understand IDoc standard, at this point we make of IDoc adapters. Here the data is packed before sending to the system

RFC Adapter:

When the receiving system throws a function out to accept data, something like API's we can use RFC
