You have executed the mappings with Change Data Capture ( CDC ) on the source...

In Oracle Data Integrator (ODI) Change Data Capture (CDC) processes, the JV$D view and J$ table are critical components for monitoring changed data capture activities. The JV$D view provides information about the CDC subscriber view definitions, while the J$ table stores the actual changed data records. Inspecting these database objects can help debug and verify that the CDC process is correctly capturing and writing changed data.
