JEST table contains object status that is either system status or a user status. Field STAT corresponds to the Object Status. Field INACT identifies whether the status is currently active or inactive and field CHGNR is the change number that identifies the change documents for an object and is incremented serially.

You could use function module STATUS_READ read active object status and STATUS_OBJECT_READ to retrieve the status profile of an object number.
