Need to create 3 relationships between 2 tables?

Hi Anmolgan ,

We can add a new step in Power Query Editor to meet your requirement:

All the queries are here:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIxABIghiWMYWxgoBSrE63kBGQbgQRBDDMYwxAq6wxWCSRADHMYw9AQKBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Type = _t, bal = _t, ty = _t, ba = _t, ty1 = _t, Bal = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Type", type text}, {"bal", Int64.Type}, {"ty", type text}, {"ba", Int64.Type}, {"ty1", type text}, {"Bal", Int64.Type}}),
    #"NameOfYourLastStep" = Table.RenameColumns(#"Changed Type",{{"Bal", "Bal.1"}}),
    Append = Table.Combine({
        Table.SelectColumns(#"NameOfYourLastStep",{"Type","bal"}),
        Table.RenameColumns(
            Table.SelectColumns(#"NameOfYourLastStep",{"ty","ba"})
            ,{{"ty","Type"}
            ,{"ba","bal"}
            }),
        Table.RenameColumns(
            Table.SelectColumns(#"NameOfYourLastStep",{"ty1","Bal.1"})
            ,{{"ty1","Type"}
            ,{"Bal.1","bal"}
            })
    })
in
    Append
