incremental refresh table properties

Hi,

if i have a model that has a handful of tables, (i.e. Policy, Claim, Claim Payments, etc...), in order for incremental refresh to work properly, i will need to setup each table to use incremental refresh, correct?  For example, if i only setup incremental refresh on the Claim Payments table based on a payment date, it will refresh based on that date change.  But if something else changes in the Claim table for example but doesn't change anything with the Claim Payment table, then the claim table will not refresh unless i have it setup on the Claim table as well.  Let me know if this is the correct setup.

thanks
