Some updates Snow Atlas users make to SAM Core can take up to 6 hours to appear in the system. This includes adding, deleting and archiving computers, agreements and licenses. Changes made will not immediately appear in the respective tabs for these items.

So as an example, if a new agreement is created, it will not appear for up to 6 hours. This is how frequently the Snow Atlas cache is refreshed. 

In the event that you need to work with the data right away, clicking Update at the bottom of the page refreshes the data immediately. In our example, this causes the agreement to appear on the tab as expected.  Beside the update button, you can see the timestamp of the last update for the table.
