Is my understanding of 'flow of message in XI' is correct ?

Hi Xi Experts

<u><b>Pl..crarify my understanding on XI full flow of message !</b></u>

If Adapter present : steps

1) Normal file will be converted as SOAP XML by using adapter

2) Adaper will send this SOAP XML message to ICM

3) ICM will convert the message into XI specific message and send to

IS?

4) All pipe line steps

5) Then it will reach the target

In case of HTTP Protocal:(SOAP)

1) Here no adapter is required and source message will be converted as

SOAP XML and sent to directly to ICM(Using plain Adapter)

3) ICM will convert the message into XI specific message and send to

IS?

4) All pipe line steps

5) Then it will reach the target

In case of IDOC SAP Sender:

1) Here no adapter is required and source message will be converted as

SOAP XML and sent to directly to ICM(Using ABAP Engine)

3) ICM will convert the message into XI specific message and send to

IS ?

4) All pipe line steps

5) Then it will reach the target

In Case of Proxies:

By using ABAP/JAVA proxies we can create XI Specific XML and send to

IS directly

This is my understanding after that pipe line

RD,ID,Mapping, Receiver adapter, Target syatem

<u><b>Pl... Correct me any where wrong in my understanding of Flow</b></u>

Thanks for spending your valuable time on my query

Hi,

>> In case of IDOC SAP Sender:

1) Here no adapter is required and source message will be converted as

SOAP XML and sent to directly to ICM(Using ABAP Engine)

Since the IDOC Adapter is ABAP stack The message is sent directly to IE.

When a source message reaches the Integration server

the messages under goes this

a) Receiver Determination:

This steps determines the system that participates in the exchange of the message.

b) Interface Detremination:

For each receiver determine which interface will should receieve the message.

c) Message Split:

If more than one receievers are found, XI will instantiate new message for each receiver.

d) Message Mapping:

Mapping to transform the source message to destination message format.

e) Technical Routing:

Bind a specific destination and protocol to the message.

f) Call outbound Adapter:

Send the transformed message to the adapter or a proxy.

Hi Kiran,

In case of IDOC SAP Sender:

no sender IDOC channel is required.....source IDOC in XML format to IE....Then pipeline steps......then target system reached.
