Filter as a measure - applying to single item

[krishna0]

Hello!

I have a problem concerning filters.

As you can see I have a single card, which task is to count items regardless of the filter from the context. I have put all necessary filters into this card as well:

But the last one, I can't come up with, is actually somehow related to disregarded slicer and I need to show items that has values in column "ClosingIteration" empty or equal to SELECTEDVALUE ( Iteration ) as per screenhsots. Iteration is taken from another table and relation looks like this: 

Names are the same, but I struggle to create a measure that will, e.g. be 1 in case of blank/<iteration name> and adding it to the filter pane. I know that filters shows aggregations and the measure should calculate such values per row, but my intuition says that it is possible, thus hard for me to achieve.

Any tips?

Hello, any advices on this topic?

I have even reproduced number of records I want to drill through to (I was thinking about filter because I can't drill from this field):

Measure_1
    =
    VAR _selectedIter =
        SELECTEDVALUE ( IterDates[IterationLevel2] )
    VAR _StartDate =
        CALCULATE (
            MAX ( IterationToDate[DateOnly] ),
            FILTER (
                ALL ( IterationToDate ),
                IterationToDate[CorrectStartIter] = SELECTEDVALUE ( IterDates[IterationLevel2] )
            )
        )
    VAR _checker =
        CALCULATE (
            COUNTROWS ( WorkItems ),
            FILTER (
                ALL ( workitems ),
                OR (
                    ISBLANK ( WorkItems[ClosingIteration] ),
                    WorkItems[ClosingIteration] = _selectedIter
                )
                    && NOT ISBLANK ( WorkItems[TagNames] )
                        && AND (
                            NOT ISBLANK ( WorkItems[StartDate] ),
                            WorkItems[StartDateDay] <= _StartDate
                        )
                        && WorkItems[WorkItemType] = "Feature"
                        && WorkItems[State] <> "Removed"
            )
        )
    RETURN
        _checker

But I can't make it filter to filter out table. Please advise.
