Hi Mei,

The Data View is saved with the data source. So as long as the table is not dropped and readded from CAS, then you should see the Data View available whenever you use that exact same data source.

If you want those changes to be automatically applied every time that data source is added to a report then that is when you should save it as a Default View.

I'll reach out to you offline in case you have additional questions.
Thank you,
Teri
