You certainly can import from a CSV file to list, list to list, a module to list, and saved view to list. Think about it this way.... When you import from a CSV file into a list you basically have 3 columns of data:
A column containing the items that will make the list
A column for the parent of these list items (if applicable)
A column for the unique code assigned to each of the list items. (if applicable)
When you import from a saved view you have the data you need for the list in the same format...
A line item containing the items that will make up the list
A line item for the Parent
A line item for the code
Now, I don't remember the activity in Model builder 2 but it seems you are confused as to what to select in the list import dialogue for parent and code.
I'd rather you send a screenshot of the module/saved view you are to use for the import so I can give you an accurate answer, however, generally speaking, you don't have to import anything in "Parent". I believe the lists were flat, meaning there is no parent. If you have a top-level specified for the P3 SKU list - for example, All SKUs- then that will be the value displayed in the grid view of the list after you import it, if not then it will be blank and that's OK
If you don't have a separate code for list items then you can use the same list items in names for the code.
This is not limited to importing into a list from a saved view, the behavior/ solution would be the same if you were importing from a CSV file
Hope this helps.
