HI @Syndicate_Admin ,

Please check the model.

DimModel;

relationships:

vcgaomsft_1-1685084142489.png

Absolute Difference = 
VAR _COL = CALCULATETABLE(VALUES('Table'[Type]), 'Table'[Model] = MAX('DimModel'[Model]))
VAR _ROW = CALCULATETABLE(VALUES('Table'[Type]), 'Table'[Model] = MAX('Table'[Model]))
VAR _ROW_COUNT = COUNTROWS(_ROW)
VAR _COL_COUNT = COUNTROWS(_COL)
VAR _DIFF_COUNT = COUNTROWS(INTERSECT(_COL,_ROW))
VAR _RESULT = IF(MAX('DimModel'[Model])>=MAX('Table'[Model]),ABS(_COL_COUNT-_DIFF_COUNT),ABS(_ROW_COUNT-_DIFF_COUNT))
RETURN
_RESULT

Hi,

Try this

 

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8s1PSc1RMFTSUXI0MVWK1UERMTRCEjHCUAMScTIyRleDossYQ5cxhi6QiKuRiVJsLAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Model = _t, Type = _t]),
Join = Table.NestedJoin(Source, {"Type"}, Source, {"Type"}, "Source", JoinKind.LeftOuter),
Expand = Table.ExpandTableColumn(Join, "Source", {"Model"}, {"Model.1"}),
Filter = Table.SelectRows(Expand, each [Model.1] <> [Model]),
Pivot = Table.Pivot(Filter, List.Sort(List.Distinct(Filter[Model.1])), "Model.1", "Type", List.Count)
in
Pivot
