Finding paths connected through a node. Data filtering

  I have a table which resembles the below. The columns explained: Main contains the name and the pathway number. The Main can therefore contain nodes called Str1 or Str2, which indicates where it...

    Try

    Connected Mains = 
VAR InitialNodes =
	UNION( VALUES( 'Table'[Str1] ), VALUES( 'Table'[Str2] ) )
VAR ConnectedMains =
	CALCULATETABLE(
		VALUES( 'Table'[Main] ),
		'Table'[Str1] IN InitialNodes
			|| 'Table'[Str2] IN InitialNodes,
		REMOVEFILTERS( 'Table' )
	)
VAR ConnectedMainsExlcudingCurrent =
	EXCEPT( ConnectedMains, { SELECTEDVALUE( 'Table'[Main] ) } )
VAR Result =
	CONCATENATEX(
		ConnectedMainsExlcudingCurrent,
		'Table'[Main],
		", "
	)
RETURN
	Result

    If I understand correctly you want a list of mains and all the nodes they are connected to. You could do another table like

    Main All Connected =
GENERATE (
    ALLNOBLANKROW ( 'Main Neighbours'[Radialnr-rettet] ),
    DISTINCT (
        UNION (
            CALCULATETABLE ( VALUES ( 'Main Neighbours'[Connected To] ) ),
            CALCULATETABLE ( VALUES ( 'Main Neighbours'[Neighbours Neighbour] ) )
        )
    )
)

Thank you, it does work for the Neighbors Neighbor column  👍. 

What I meant with a second column, was that a column that sums the total of filtered.

In this: Main + Neighbor of Main + Neighbors Neighbor. This makes the table large. But, I can use this new column to connect to the picture table and then have the problem solved. is it possible ?
