Pipeline Steps and JCo Calls

[Former Member]

Hi All,

I wanted a few links which can provide me with indepth knowledge of these two points

1. Pipeline Steps in XI

2. JCo Calls during processing of messages

I am looking specifically to understand the message processing in steps where the Mapping is called and returned to ABAP IE. i mean the Enchanced Receiver Determination / Interface Determination Steps

Hi Aditya,

Pipeline steps are :

Receiver Identification

Determine which system(s) should participate in an exchange with the

incoming message.

Interface Determination

For each receiver system determine which interface(s) should receive a

message.

Message Branch

If multiple receivers are found, XI will instantiate a new message for each

receiver.

Request Message Mapping

Call the mapping program to transform the message structure to the receiver

format.

Outbound Binding

Bind a specific destination and protocol to the message.

Call Adapter

Send the transformed message to the adapter or proxy

Check this weblog for full details on how a message flows in XI:

Hi All,

Thanks for your response.

But i was look at specifically the following inputs

1. Are there multiple JCo Calls made in case we have multiple message mappings?

2. DUring the JCo Call what are the function modules / RFC dest being used to execute the mapping

3. While executing mapping what are there any specific place from where these mapping are executed, propably we have an mte file for each mapping / a converted java class for each mapping

Hi All,

I have a quick doubt as well. After interface determination step and a call is made via JCo for executing the mapping, in case we have 3-4 mappings in a interface determination, wll there be 3-4 JCo Calls, will the payload after each step come back to ABAP Engine?

Hi All,

i dont think so these questions are the most toughest of all, that no one is giving it a try.

Anyways i thought i will create a new thread but didnt want to increase the thread count.

I would like to know how a mapping is executed. What are the clases / functions that are called?

Can any one shed some light on this
