How to handle early arriving Facts or late arriving Dimensions

There are three common options available to handle early arriving Facts or late arriving Dimensions.
Option 1:
Do not load fact - Redirect/ignore the records
Option 2:
Load Fact with an unknown key (0 or -1), but make sure that dimension already have unknown member

Option 3:
Load Fact with create inferred member - Inferred members exist when a fact table references dimension members that are not yet loaded. When data for the inferred member is loaded, you can update the existing record rather than create a new one.
