Hi Manju,
Thanks for reply.
User1 will download notification based on plant.
User1 will then assign maintenance work center then it will get assign to user2 and it will get removed from user1 and synchronize so user2 can download.
#1 #2 Same notification will not be with user1 and user2 at a time, so it should work offline.
#3 Assignment for user1 will be based on plant and user2 will be based on maintenance work center. #3 answers #4.
Regards
Manish
