Power BI DAX : CROSS JOIN between two tables based on a variable filter

Hi  snph1777  ,

Here are the steps you can follow：

1. Create calculated column.

Desired Output table =
var _david=
SELECTCOLUMNS('Table (2)',"UserName","david","Ports",[Ports])
var _john=
SELECTCOLUMNS(FILTER('Table (2)',
[Sement]=CALCULATE(MAX('Table'[Segment]),FILTER('Table',[UserName]="john"))&&
[SementID]=CALCULATE(MAX('Table'[SegmentID]),FILTER('Table',[UserName]="john")))
,"UserName","john","Ports",[Ports])
var _mike=
SELECTCOLUMNS(FILTER('Table (2)',
[Sement]=CALCULATE(MAX('Table'[Segment]),FILTER('Table',[UserName]="mike"))&&
[SementID]=CALCULATE(MAX('Table'[SegmentID]),FILTER('Table',[UserName]="mike")))
,"UserName","mike","Ports",[Ports])
VAR _1=
SELECTCOLUMNS(FILTER('Table','Table'[UserName]="jill"),"1",[Segment])
VAR _2=
SELECTCOLUMNS(FILTER('Table','Table'[UserName]="jill"),"2",[SegmentID])
var _jill=
SELECTCOLUMNS(FILTER('Table (2)',
[Sement] in _1&&
[SementID] in _2)
,"UserName","jill","Ports",[Ports])
return
UNION(_david,_john,_mike,_jill)

2. Result.
