Send acknowledgement to R/3 system from with which receiver adapter

Question

Hello,
simple question:
A lot of answers are here but...
not really clear to me as general answers.
From where can I generate /get an acknowledgement to send it back to a IDOC sender?
Ok, I understand: IDOC -> XI -> File is able to send back a system acknowledgement from file adapter
Same for IDOC -> XI -> IDOC (as usual)
Is any system or applic. acknowledgement from any adapter suitable? (Or where are restrictions?)
Do I have to add then in NOALE prg. entry for the acknowledgement-sender ?
Best regards
Dirk

Hi Bhavesh,
this is clear to me I think.
But this  guide explains Acknowledgements with R/3 -> XI -> R/3!
My question is:
I have a scenario
R/3 -> IDOC -> XI -> whatever -> anysystem
I want to send an acknowledgement back to the R/3!
Which are the restrictions? Where do I generate the ackn. if the receiver syst is not able to generate it?
If the receiver can send something back, how move that to
Reason for the question:
I have here a nice Tutor where an IDOC to file scenario provides the IDOC sender with an ack.. But all what is to do is adding the Ackn.entry in SXMB_ADM and adding a IDOC receiver for the ALEAUD in Int.Directory!
How does that work? And is this working for all receiver adapters?

Dirk
