Idoc to file scenaro ( sending IDOC as it is to NON-SAP)

Question

Hi Experts,
I am doing idoc to file scenario.
I am having SAP R/3 system with 3 clients(100, 200 & 300), IDOC is comming from SAP R/3( any one of the client)
In this is scenario, I am sending IDOC-XML as it is to the NON-SAP system.
I heard that, i can do in 3 ways. those are
1. Without any repository objects: you can go ahead with No interface mechanism on the target side.
2. Without message type: create a message interface whose message type would be idoc itself
3. With message type: export the IDOC as xsd file and re import the xsd file as an external definition.
If i  go without IR objects,Please tell me whether i need to create Interface objects(i.e. DT,MT & MI) & Mapping objects (MM & IM) or not for the reciever.
MY ASSUPTION:
   step1: I will import the IDOC into IR.
   step2: Directly i will go to the ID without desiging any object in IR ( is it ok).
  Is my assuption or correct or not?, please tell me.
So please tell me the entire scenario how to achieve this.
Please help in this issue.

Hi Laxmi
1. Without any repository objects: you can go ahead with No interface mechanism on the target side.
-- Not Possible
2. Without message type: create a message interface whose message type would be idoc itself
-- No need for the Message Interface for IDOC. You will directly import the IDOC and do the Mapping
3. With message type: export the IDOC as xsd file and re import the xsd file as an external definition.
-- This is Possible. you are export the IDOC as XSD File and reimport the same. so there is no difference. If you are going to change the IDOC Structure then this is possible.
Here I am sending some links which are useful for IDOC to File Scenario. Please go thru the links given below..
While doing an IDOC -> XI -> File scenario, The Points to noted are:
1. You don’t need a DT, MT or a message interface for the IDOC as it itself acts as the Message Interface.
2. You import the IDOC and use the same in your mapping.
3. In this configuration note that you don’t have a sender agreement as you don’t have a sender IDOC adapter.
If it is that you wanted to send an IDOC from XI (File to IDOC) , then in this case:
points 1 and 2 will remain, but the 3 will not. You will need a sender agreement for the file and a receiver agreement for the IDOC.
IDOC -> File scenario ref:
IDoc-XI-File scenario
File -> IDOC ref:
File to IDOC
To be able to trigger your IDOC from the SAP ISU system, you will have to set the partner profile in we20. Select your Business System (mostly under Logical system) and then create Outbound entries for whichever IDOC you want to trigger.
You define your basic type also in your partner profile settings, Please go thru the following links to get a better idea about partner profile:
