Dynamic calculation based on filter and grouping

Hi all

 

I have measure formula like

divide(SUM('Table1'[Col1]),SUM('Table1'[Col2])+SUM('Table2'[Col3]) ,0)

 

Problem is with 'Table2'[Col3] field - it should be excluded from formula in case if some attribute, Let's say 'Table3'[Attr1] are added to grouping or filtered. 
I tried using SELECTEDVALUE():

VAR compValue = SELECTEDVALUE(Table3'[Attr1],"Total")

RETURN
SWITCH(
compValue,
"Total", divide(SUM('Table1'[Col1]),SUM('Table1'[Col2])+SUM('Table2'[Col3]) ,0),
divide(SUM('Table1'[Col1]),SUM('Table1'[Col2]) ,0)
)

but it works well for grouping - when only one or several values of 'Table3'[Attr1] selected.
But in case if there are no grouping by 'Table3'[Attr1]  and data are filtered by this attribute it doesn't work well. Because according to requirements it also should calculate as divide(SUM('Table1'[Col1]),SUM('Table1'[Col2]) ,0) , but it doesn't since there are selected more than one Table3'[Attr1] values .

Is there any way to detect, that there are any filter by some attribute added to report?

    cyberirbis , Try like

     

    VAR compValue = maxx(filter(allselcted('Table3'),'Table3'[Attr1]= "Total"),'Table3'[Attr1])

    RETURN
    SWITCH(
    compValue,
    "Total", divide(SUM('Table1'[Col1]),SUM('Table1'[Col2])+SUM('Table2'[Col3]) ,0),
    divide(SUM('Table1'[Col1]),SUM('Table1'[Col2]) ,0)
    )

      sorry,  I don't get what this expression for:
      VAR compValue = maxx(filter(allselcted('Table3'),'Table3'[Attr1]= "Total"),'Table3'[Attr1])

      This will not work at all since 'Table3'[Attr1] is integer

      In my example
      VAR compValue = SELECTEDVALUE(Table3'[Attr1],"Total")
      "Total" it's not value of 'Table3'[Attr1] field, it's just value to identify total row with several 'Table3'[Attr1] values  for further using in switch function
