Queue Mechanism Doubts

[Former Member]

Dear All

I am so much confused about queues Mechanism

how the queues get populated ,processed and gets stuck incase of error

in case of file to idoc message processing can be divided to FILE to XI and XI to SAPR3

and here are my doubts

a)which queues will be queues used (ie either outbound or inbound queues)

for communication between file and XI?

b)for communication between XI and R3 will queues be used or some a TRfc call be used.

if it is queues again will it be inbound or outbound queues?

c)in SAP R3 any queue Mechanism is used or TRfc calls used for processing the idoc ?

Please Clarify and correct me if my understanding is incorrect?

Thanks and Regards

Satish
