1. Compare Active Subscriptions (DB) with the current request
   1. Find delta
      • we have the same subscription if we have the same combination of 
        1. cmhandle AND xpath filter AND datastore
   2. Update when there's overlapping
      • updating the status in the HZ map from 'PENDING' for duplicated request(s)

A/C

• Implementation proposal agreed with team 
  1. Finding delta
  2. Data structure to keep track of all new 'Subscriptions'
     1. Update map (will be used for NCMP to DMI flow)
     2. PENDING --> ACCEPTED/REJECTED
     3. Will the subscription already existing be added to the 'tracking map' as 'ACCEPTED' or not added at all?
