Message interface

[Former Member]

Hi,

I have a scenario R/3 <-- XI <-- Legacy. This might be really basic but the message interface of the legacy system would be of category “Inbound”. ?? I get lost in sometimes judging the directions of the message interfaces. Is there any cardinal rule in setting the direction of these interfaces?

Hi,

it is inbound for legacy system here.

Some tips:

If message is coming <b>into XI</b>, then it is called as Outbound Message Interface.

If message is going <b>out from XI</b>, then it is Inbound Message Interface wrt other system is concerned.

don't confuse here

If message is coming into XI, then it is called as Outbound Message Interface.

--If the message is coming into XI , in this case the message is “coming into XI “ from legacy right. So how is it inbound? This could be a dumb assumption but I would appreciate a clarification.

If message is going out from XI, then it is Inbound Message Interface wrt other system is concerned.

Is your scenario is R/3 ->XI->Legacy right ?

If so , Message is coming into XI from R/3. Then it is outbound interface.

Now from XI, message is going out to Legacy SYstem. Then Inbound Message interface wrt Legacy system

Hi,

For me it looks like that:

a) interfaces

outbound - this message which initialize communication

(thanks such understanding you can avoid confusion during synchronous communication)

inbound - this interface which not initialize communication

b) channel (it can be also confusing for beginners)

sender - is always this one which tranfers to XI XML format

receiver - is translating from XI XML to other (like file, idoc, rfc)

Oops sorry, the scenario is from legacy into XI and from XI into R/3. So messages come form legacy into XI and then XI sends into R/3. Sorry about the confusion. So in this case the message interface for the legacy would be "Outbound" then ??

Hi,

of the application system (legacy)
