I am trying to reuse a power query to pull information from another power query. It seems like there are multiple way of doing this. I see two ways of doing this from this question. I also see it in my own spreadsheets. In my spread sheet I apparently have:
Source = Excel.CurrentWorkbook(){[Name="Project_List"]}[Content],
In other queries I have:
Source = Project_List,
Is there an advantage to one method or the other?
Ultimately what I am hoping to achieve is to query the data once across the network, dump it into a table A then in follow up queries keep referring to table A and not pull the data across the network for the subsequent queries.
I noticed that when I was building my most recent query using the Source = Project_List,, at each step of the follow up query it was loading actually reloaded all the files that Project_list query loads.
Is this just part of the building process? Or If I have one query A that loads across the network and 5 follow up queries that refer to query A will power query / excel be reading the across the network 1 time or five times?
What is the proper way in Power Query to refer to an existing query and reduce data pulls across the network?
Power Query will always stream data from source - see here for a fuller understanding.

The only way around this is to use Table.Buffer or List.Buffer to temporarily cache the data.
For this line, then presumably you have another query named Project_List which in turn gets your data from the workbook?
Source = Project_List,
