SAP best practices: Reuse communication channel

[Former Member]

Hi expert,

in some of my projects I reuse CC for multiple scenarios, in other projects I'd create a separate CC for each scenario even though I can reuse an existing CC. I haven't really thought about this issue, but now I need to ask myself and you guys what is SAP best practice whether or not to reuse CC in PI?

Let's say PI communicate with ECC via abap proxy (XI adapter), there are 20 scenarios with XI adapter, I can either create only one CC, and reuse it in the 20 scenarios, or create 20 CC, one CC for each scenario. Technically both works, but what is SAP's recommendation on this? I can't find any document on this from SAP.

What is behind the scene for CC? does it mean a connection would be created each time it is used? in that case, reuse would be better for performance, because we can reuse the connection (if it still exists), and save time creating one.

What is the pros and cons of reuse and not reuse CC?

Any expert can comment on this?

Thanks

Jayson

Jayson,

If precise control is needed, create individual channels (If there are individual channels for each interface, some message flow can be stopped without impacting other interfaces).

Else, reuse channels (reuse is efficient and easy to maintain).
