Thanks for Information. But by refresh I was talking about refresh of metadata of data query i.e for example any change in label at source metadata should reflect in data query .Currently for existing column used in query it wont reflect but if we drag the same column after making change it reflect. Got information from other post that Query is stored both as metadata and in stored server. Also checked with SAS consultant , currently unfortunatley there is no way out to update/refresh query metadata programatically . Currently we are doing it manually comparing metadata for source and target and updating 'labels' in query manually to be in sync.
