Question: What is the primary purpose of the Local Record Sequence Number field in a Charging Data Record (CDR), as generated by a network function?
Option 1: To uniquely identify the type of CDR (e.g., partial or whole) across all network functions.
Option 2: To enable the identification of missing records during post-processing within the scope of a single network function.
Option 3: To provide a global unique identifier for every CDR across all network functions in a telecom network.
Option 4: To specify the sequence of NF Consumer Information usage for charging services.
Explanation: The Local Record Sequence Number field allows for the detection of missing records during post-processing activities within one network function, ensuring data integrity and completeness at that level.
