Hi Maximiliano,
I don't think a transport should trigger a Full CPA Cache refresh. Only a Delta refresh.
You can control whether the cache is automatically updated after a transport with the Exchange Profile/AII Service parameter com.sap.aii.ibdir.core.ctstransport.autoActivation.default = [true|fasle]
If you set this to false, you will then need to manually update the cache after you have made the necessary changes to the Comm Channel parameters (some mandatory fields are not transported).
See note 1345425 Skip Import and auto Activation feature for XI transports, for details.
Regards
Mark
