Regarding B2B 11g Channels

Question

Hi Everyone,
I am new to B2B and it would be great if some one can clarify on the following questions .
1) Can a internal Delivery channel be inbound to B2B where in B2B is given the data by the backend application and B2B need not fetch it through an internal listening channel?
2) Can a Remote trading partner send a message to Oracle B2B based on the External Delivery Channel configured to it ? Here B2B is not fetching or listening for inbound data
from Remote trading partner(through an external listening channel) but instead the remote partner is sending i.e. triggering the interaction.
3) Does an internal delivery channel participate in an agreement ? My understanding is that an agreement is between Host trading partner and remote trading partner
I have read the other forum threads and blogs but could not get a clarification on the points
Thanks in anticipation

Answer 1

Hi Mainak,
1) When I look into an Agreement I notice that we have under channel column 2 sub columns called From and To. So what is the Significance of that ?
In the outbound from Oracle B2B's case I understand that the To Channel column will contain the partner's channel name. But am not sure when will the From channel be populated because any message coming into B2B is through listening channel and listening channel do not participate in an agreement.While creating agreement, you will find channel drop-downs in both the trading partners section.
The channel drop down in Host TP section is used to select the "INTERNAL" host trading partner channel (created under Host TP --> Channels tab with INTERNAL checkbox selected). This channel is used to pass the incoming documents (from remote TP's) to middleware/back-end. So you may only select a channel from this drop-down in an INBOUND scenario where the incoming message has to be passed to back-end and that too without using the default internal channel (IP_IN_QUEUE or B2B_IN_QUEUE).
The channel drop down in Remote TP section is used to select the remote trading partner specific channel (created under Remote TP --> Channels tab) or common outbound channel i.e. "EXTERNAL" host trading partner channel (created under Host TP --> Channels tab with INTERNAL checkbox NOT selected). This channel is used to pass the outbound documents (from middleware/back-end) to the specific partner. So you may select a channel from this drop-down in an OUTBOUND scenario where the outbound message has to be posted to Remote TP.
2) Then in an agreement can we have the scenario of both the To and Form channels of a agreement populated ? Yes, there may be a scenario where you have to select channels from both the drop-downs. For example, an Inbound ebMS agreement. In case of INBOUND ebMS, your B2B will have to pass the incoming document to back-end as well as it has to post an ACK back to TP. Same is the scenario with any standard Exchange which supports exchange level ack (like RNIF, AS2 etc.).
