Hi,

Please give me you inputs on these below questions

1. What is the main difference between RFC and IDOC Adapter and when we go for RFC and IDOC with ex?

Idoc and BAPI are both are SAP-objects.

Idoc adapter used for ASync- communication.

Rfc adapter used for sync-async communication

Check this For choosing the Right Adapter while dealing with the SAP Systems

/people/ravikumar.allampallam/blog/2005/08/14/choose-the-right-adapter-to-integrate-with-sap-systems

2.What are IDOC you knw?

IDOC ADAPTERS are based on INTEGRATION ENGINE of ABAP STACK

3)Sender Agreement is required for Idoc adapter? Why?

NO, Sender Agreement is not required for IDOC adapter, instead we will do settings from R/3 to XI system, so we don't have any option to create an IDOC adapter in sender side, we will trigger the idocs through we19. and transfer the data.

4)Context handling.

Please refer these:

http://help.sap.com/bp_bpmv130/Documentation/Operation/MappingXI30.pdf

Pages 62-74

http://help.sap.com/saphelp_nw70/helpdata/en/bd/ca1105c81c6742a0f8c8d49f8834bf/frameset.htm

Refer section: Structure Mapping by Setting the Context

5)What is Global container in SAP XI?

Container object---> can be only used in the function it is defined in

Global container > it can be used and remain visible across the the different function

Global container

in the old days it was used to store objects in mappings

now we can use global variables instead

Container Object: This object enables you to cache the values that you want to read again when you next call the same user-defined function .

From SP14 and above avoid Global Container. Use Java Section of Message Mapping to define Global Variables and to used them in your UDF's.

6)When we go for Correlation what is the use of correlation in BPM's?

Check the Links for BPM concepts.
