Hi to all,
I appreciate all the answer which is given above,
But I would like to add some very important concept of
IDOC:-
IDOC : Intermediate Document
Purpose : It will send the record from one sap system to
another sap system and aweless It will fetch the data from
remote SAP R/3 to current SAP R/3 system.
Sending of record or data from one SAP R/3 to another is
is also possible by RFC but fetching of data from remote
R/3 is not possible, so only in that case IDOC'S Comes
under existence.
IDOC :
It is a collection of segments (child segments and master
segments)
It is a 16 digit no. which is generated automatically after
execution.
It is one of the technique for transferring and receiving
record.
It is a collection of 3 things data records, control
records and status record.

IDOC can be created by existing segment or userdefine
segment. Creating logical system, creating model view and
creating partner profile are some of the steps which are
used in creating outbond and inbond processes.
status record - 50,53,62,64 gives success status
56 gives wrong status
TCODE : SLDB,WE20,BD64,WE30, WE80,WE81 are some of tcode
which are used in IDOC generation.
