Modify the time measure that the dynamic table’s content should lag behind updates to the base tables. Modifying freshness may affect the refresh mode of the background job, which may change from continuous mode to full mode, or from full mode to continuous mode, or remain unchanged. In any case, alter freshness will stop the current refresh job and create a new job with the updated freshness.
