Measure to identify selected items using separate slicer table

[Anonymous]

Dear community,

I'm looking for assistance in making a measure that identifies which items have been selected by using a seperate slicer table

I have Tables as follows:
NetworkTable

ID	FromStep	ToStep	FromSeries	ToSeries	Value
1	A1	A2	A	A	0.5
2	B4	A2	B	A	1
3	A2	C5	A	C	0.7
4	A2	A3	A	A	0.9

SeriesTable

Serie	Serie_Name
A	Series A
B	Series B
C	Series C

I have a slicer using the SeriesTable[Serie_Name] column: Series A | Series B | Series C
The slicer should have 1 or more selections active.

My desired result is a measure 'IsSelected' that would give a result like this:
If the User selects 'Series A'

ID	FromStep	ToStep	FromSeries	ToSeries	Value	IsSelected
1	A1	A2	A	A	0.5	1
2	B4	A2	B	A	1	0
3	A2	C5	A	C	0.7	0
4	A2	A3	A	A	0.9	1

If the User selects 'Series A' and 'Series C'

ID	FromStep	ToStep	FromSeries	ToSeries	Value	IsSelected
1	A1	A2	A	A	0.5	1
2	B4	A2	B	A	1	0
3	A2	C5	A	C	0.7	1
4	A2	A3	A	A	0.9	1

IsSelected = 1 when either FromSeries or ToSeries is matching the Slicer
Due to various other exisiting relationships, I cannot make a relationship between these two Tables.
All rows of the NetworkTable should remain unfiltered.
I've been experimenting with 'SELECTEDVALUE' and 'HASONEVALUE', etc. but without a lot of success.
Any suggestions how I can accomplish this would be greatly appreciated.

@Anonymous , make sure SeriesTable is an independent table then try a measure like below in visual or visual level filter

new measure =

var _tab = summarize(allselected(SeriesTable), SeriesTable[Series])

return

countrows(filter(NetworkTable, NetworkTable[FromSeries] in _tab || NetworkTable[toSeries] in _tab) )

@amitchandak , thank you. That did exactly what I needed! Works like a charm
