I wonder if I can create a PIT from a SAT that keeps a Dependent Child key?
The Dimension Key is unclear to me. Is it a field coming from the stage model? Or is it creating a "surrogate key" that can be used in the fact/dimension tables afterwards?
Best regards

How have you modeled the Dependant Child Key? There is a page in our Wiki, check it here. If you have followed this implementation, the satellites should not deviate compared to a non-dependant child construct, and can therefore be used in PITs as usual.

The dimension key is a surrogate key generated in the loading process of a PIT, out of the hash key and the snapshot timestamp. It is used for incremental loading of the PIT. The option in the macro will just influence the name of the new column. Hope this helps for understanding!
