    Hello yannaingoo 

     

    If in desktop, as a developer to avoid loading massive data when I refresh, I would normally set up a Parameter in Power Query like DevMode (True/False), and apply filters based on below logic to limit rows from Power Query (once the Parameter is created, you can also set up via UI)

     

    if DevMode then
    Table.SelectRows(Source, each [Date] >= Date.AddDays(DateTime.LocalNow(), -30))
    else
    Source


    For details please refer to this YouTube Tutorial from 'Guy In a cube'

    Hope this gives you some ideas:)
