using function module idoc_outbound_<message type>. we  can 
set the break point for this function module.

EDIDD to store data records.
EDIDC to store control information.
EDIDS to store status of IDOC

EDID4 is the table to store data segments (EDIDD is the 
structue, not a table)

According to my knowledge in SAP XI we have so many kind of 
control levels to process the message. For instance i will 
discuss on few points, like
1) Here using XI we can communicate with the SAP or Non-SAP 
at sender side or reciever side.
2) XI supports both Syncronus and asyncronus communications
3) in XI we can find the status of the message where it is  
   during the process of Message processing.
4) We have so many kinds of monitoring techniques.
5) Here we can have N number of senders and N number of 
   recievers based on your requirement.
6) It supports to process multiple messages at a time from 
   different senders to multiple recievers.
So I feel we cant perform all these things in 
Interfaces.That is the reason XI come into picture.

Still if u get any thing other than this please mail me at 
cravisap@gmail.com

Hi , 

Master IDOC : This idoc collects all the required data into 
single IDOC and this is temporarily stored in memory. 

Communication IDOC: there can be n number of communication 
IDOCs generated. This comes into picture after the Master 
IDOC is validated from the distribution model . And this 
IDOC is stored in database table . you can see this IDOC 
from we02 tcode. 

Best Regards, 
Suresh .

Inbound process strats when application data is creatred
inthe  database.

Based on the given input outbound program trigers ,reads the
application data from the database& generates the master idoc.

Master idoc is the data inthe internal table. master idoc
data will not save any where in sap.

comm idoc is the physical idoc which is reciever specific.

1 master &communication idoc

5 master idocs and the number of communication idocs is 
based on the number of recipient systems which is mention 
in the customer distribution model of that message..

Hi, 

As per my knowledge, you cannot send the single IDOC to 
multiple system . At a time an IDOC can be directed to only 
single system . 

Thanks & Regards, 
Suresh

if you are sending one idoc is to more systems you are 
create one sender logical system and more recive logical 
systems in T.CODE is SALE. then yoou are send In T.CODE 
BD64.

CHANGE POINTERS:ACTIVATION OF CHANGEPOINTERS FOR MESSAGE 
TYPES.


CREATION OF IDOCS FR CHANGE POINTERS.

CHANGE POINTERS CONCEPT IS BASED ON CHANGE DOCUMENT 
TECHNIQUE,WHICH KEEPS A TRACK ON ALL THE CHANGES MADE TO 
KEEP DOCUMENTS SUCH AS 
MATERIALMASTERS,CUSTOMERMASTER,VENDORMASTER.
ALL THE CHANGES CREATIONS DONE TO THOSE DOCUMENTS ARE 
STORED IN CHANGE DOCUMENT HEADER TABLE.
TABLE NAME:CDHDR

Message control : Every Idoc that is trasnferred is 
associated with the message type.

Message type defines the type of data the idoc is 
containing.

See for example : If i am transffering material data then 
my message type would be MATMAS it is predefined.

in the same way if i am tranfering Customer data then my 
message type would be DEBMAS.

And So on.

to create a message control:

if you want to send a po go to  <me21n> select/create the 
po.no click /messages/ enter details of output type, medium 
and partner , also configure the same in <nace>.

go to <we20>
select the vendor and double click the message type will 
take to another screen.
click message control and enter the details with respect 
to /messages/ and give the process code & save.

message control will be created.

msgcontrol is mainly used for transactional data to enerate 
the idoc.frist u identify wt type of data u want transfer.
for using msg control we20 tcode inbound 
parameters,outbound parametes,mudium in which vrous 
componetsu fill it

it should be handled by technical consultants

I Understand the question as to Handle the IDOC after 
processing which was showing with error messages.

If that is the case. 

Reprocess the IDOC by populating the missing data/ Correct 
data (Depends upon the type of message showing in the idoc 
status). 

To re-process the IDOC use - WE19 (Tcode)
    OR
Re-trigger the IDOC to re-triggering the message output
(Outbound case).

ALE+WORKFLOW HANDLES ERRORS.

idoc exetension is nothing but a to add the some more
functinality to the basic idoc. that is called the idoc
exetension. this is done by using the transaction code we30.
and go select the radiobutton like "exetension".

exextened functionality and use more functionality to the 
basic idoc is nothing but idoc extention.

Idoc extension is nothing but adding extra functionality to 
the existing message type.

Steps : 

1.Go to Tcode WE30.
   In that click the radiobutton extended.Execute and save.
2.Go to Tcode we20 (create patner profiles).
   in this after entering the patner profile and when u 
press the enter button then it will direct u to another 
page wherein u enter the message type and if it is the 
extended idoc then extended message type also need to 
specified.

Adding extra functionality to basic idoc is the concept of 
extended idoc.
go to we 30 click on extension idoc radio button

idoc is nothing but intermediatery documentation for inter 
company posting purpose its used

To create an Idoc.
1. Create message type.
2. Attach basic types of IDOC to message type.
3. Attach FM to the message type combination of IDOC types
4. Creat a process code and attach message type to it.
5. Create a Partner function through WE20. Add an message  
   type in the outbound paramater.
6. Have an entry of port name and basic types (IDoc types) 
   in the outbound options tab
7. Add and an entry in the message control option with the 
   output type (ME21N- Output type) and the process code.
8. When you db click on the process code the FM should 
appear.
9. When an output is triggered in the ME21N transaction wit 
the EDI output medium. The idoc will be triggered

create segment using we31 x-code
create idoc(basic type ) using we30 x-code
then use we81 and we 82 x-codes
