Hi Sandesh
This is as designed. As said above, if you are in Ehp4 or above, you can change this behaviour
But more than that, will you be ok with a posting happening in LL and not in NL? I think you must keep the open periods in sync for both of them
the option to maintain separat posting periods for NL makes sense only if you have to make a local posting to it

PS- Request you to close your threads. You can close it by marking any answer as CORRECT or marking the thread as ASSUMED ANSWERED. For a workaround solution, you can mark HELPFUL, if there is no direct solution available
this helps others to know how it was fixed
