The failure case#
If you use a Disaggregated Process to supply an input and then do not model its upstream chain, the upstream impacts are simply absent from your results.
Aggregated Processes avoid this by including the upstream chain by default.
Filtering by type#
In the Library or when adding a node, click Add filter, then Process Boundary, then select the type you want.
Not every Process has a version in all three types.
