OM to OSS Integration - RMCS Impact

Hello Community members,

We have following queries with regards to standard OM to OSS integration:

1) Can we perform amendments directly in Subscription Management after enabling new OM to OSS flow ? If yes, does amendments flow to RMCS appropriately ?

2) When Subscription lines gets booked in Order Management, system is sending those lines to RMCS and starts recognizing revenue even though subscription is not activated ? is it an expected system behavior ? Is there any way to prevent this ?

Thanks
