Thanks Praveen. Maybe I need to be a little clearer here.
We have two SA-aware components in the same SI. We use saAmfCSIDependencies to make sure that the ACTIVE assignment for one CSI always precedes the other. This works as we expect. But, we notice that it is not the case when the STANDBY assignment is done. And I don't understand why. I understand for QUIESCED/QUIESCING that the order should be reversed, but why not have the same order for STANDBY as ACTIVE for SA-aware components? I don't see a mention of NPI anywhere in 3.8.1.3, so I'm not sure what you mean here.
