Hi @619SK 

You can put the following code to advanced editor in power query

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCihKLcvMLy1WCE9NzVaK1SFXxLm0qCg1r2TABXwSi4nhxQIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Week = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Week", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Week"}, {{"Count", each Table.RowCount(_), Int64.Type}, {"Data", each _,type table}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "WoW% ", each (List.Min(Table.SelectRows(#"Grouped Rows",(x)=>x[Week]="Current Week")[Count])-List.Min(Table.SelectRows(#"Grouped Rows",(x)=>x[Week]="Last Week")[Count]))/List.Min(Table.SelectRows(#"Grouped Rows",(x)=>x[Week]="Last Week")[Count])),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Week"}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Removed Columns", "Data", {"Week"}, {"Week"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Expanded Data",{"Week", "Count", "WoW% "})
in
    #"Reordered Columns"

Output

Hi @619SK 

Can you please try below measure, please replace the column name in DAX 

Previous Week = Calculate(Count(table_name),Column_Name="Previous Week"))
Current Week = Calculate(Count(table_name),Column_Name="Current Week"))
Last Week = Calculate(Count(table_name),Column_Name="Last Week"))

Last Result = Divide((Current week - last week),Last Week)
