Communication Channels for IDOC scenario

[Former Member]

Hi!

I have a conceptual question regarding the communication channels within IDoc scenario.

Case 1:

- File_to_RFC scenario

Here I defined a File communication channel from business system A.

1a) For which system (business system A or B) do I need to define a IDoc communication channel?

1b) What is the RFC destination and Port I need here?

Case 2:

- IDOC_to_IDOC scenario

2a) Do I need in this scenario only one communication channel for business system A?

2b) What is the RFC destination and Port I need here?

Thank you very much!

Ans 2a. You will need only one Idoc receiver CC at receiver business system that is B.

Ans 2b. RFC destination will be for connectivity from R3 to system A maintained in System A and then again in XI for connectivity from XI to system B.

Thanks!

in this case no IDoc CC is involved. All you need is a File sender adapter and RFC receiver adapter

in this case you will need a IDoc receiver adapter only.

The basic settings:

In XI

SM59 - R3 connection pointing to R3

IDX1 - define the port with the above dest.

In R3

SM59 - R3 connection pointing to XI

WE21 - define the port with the above dest.

WE20 - Partner profile type outbound/Inbound

Hi!

excuse me.

In case 1) I mean the case: File_to_IDoc scenario.

1a) For which system (business system A or B) do I need to define a IDoc communication channel?

1b) What is the RFC destination and Port I need here?

Thank you!

you will need a IDoc receiver channel for your target system since it is receiving the IDoc.

Regarding the Destination, please look into my early post.
