Change source from Dataflow to Server

Hi community,

I’m looking to change the source of an already built report from dataflow to server.

I tried on settings > Option but it just won’t let me change.

Can anyone help me on advanced query?

• From server the source code is “

let

    Source = Sql.Database("ServerName", "DataBaseName"),

    dbo_V_Table name = Source{[Schema="dbo",Item="TableName "]}[Data]

in

    dbo_V_Table

“

• From dataflow the source code is “

let

    Source = PowerBI.Dataflows([]),

    #" workspaceIdNumber= Source{[workspaceId=" workspaceIdNumber "]}[Data],

    #" dataflowIdNumber = #" workspaceIdNumber "{[dataflowId=" dataflowIdNumber "]}[Data],

    Table1 = #" dataflowIdNumber "{[entity="Table"]}[Data],

    #"Filtered Rows" = Table.SelectRows(Table1, each true),

….

In

  #"Filtered Rows3"
