First 2 columns are parts of fact table, so does not require any transformation.

But for all dates and amount, need to unpivot which will be in column3 and column4.

Output should be something similar to below table.

Thanks in advance.

    NewStep=Table.Combine(Table.TransformRows(Table1,each let a=Record.ToTable(_) in Table.Combine(Table.Group(Table.Skip(a,2),"Name",{"n",each #table(List.FirstN(a[Name],2)&List.TransformMany({1..Table.RowCount(_)},each {"Attribute","Value"},(x,y)=>y&Text.From(x)),{List.FirstN(a[Value],2)&List.Combine(Table.ToRows(_))})},0,(x,y)=>Byte.From(Text.EndsWith(y,"Date")))[n]))
