Hello Lakshmi P,
Welcome to the Microsoft Q&A forum.
RunId
A RunID is a unique identifier for the particular pipeline run. Each pipeline run will have a RunID which you can use for querying the logs and finding status of the pipeline activity.
CorrelationId
A Correlation ID is a unique identifier that is added to the very first interaction (incoming request) to identify the context and is passed to all components that are involved in the transaction flow. Correlation ID becomes the glue that binds the transaction together and helps to draw an overall picture of events.
The CorrelationId is used to group related pipeline runs, activity runs, and trigger runs together, while the RunId is used to identify each individual pipeline run, activity run, or trigger run.
The RunId does not change for the same pipeline run, activity run, or trigger run, unless they are deleted and recreated.
