Hi all,
I have a scenerio whereby I have a Master table (MasterCodes) with a list of codes organised by Identifier TYPE (Catalogue/SubCat/Format etc). Currently I split this table into 10 individual tables, referencing the Master table, to create a table for each Identifier.
e.g.
let
Query = MasterCodes,
TYPE = Table.SelectRows(Query, each ([Identifier] = "SubCat"))
in
TYPE
My model is getting quite large and PBI takes ages to respond, so I'm trying different ways to improve.
Is the above method the best way, or should I create a dax table with GROUPBY? What performance benefits would I get from either?

Hi @Anonymous ,
I prefer you to use Table.selectrows() in power query:
In conclusion, if your model is very large, using power query to clean data in advance is better than using dax directly, although both of them can get the same result finally.
You can also refer these articles about differences between dax and power query in details:

Hi @Anonymous ,
First thing, why you are creating multiple tables for different TYPE from your master table?
What kind of visualisations you are trying to achieve using these individual tables?
Please answer above in order to understand what you are trying to acive in these tables.
Thanks,
Pragati
