Filter based on rank

[SteveCampbell]

For some reason can't work this out

I have a table with products 1,2,3,4,5,6

I can filter on any combination

I have another table with selected product, based on rank of the product ID

I'm trying to write a measure to say which product I have selected - 

For example:

 products filter = 2,4,5

 selected product = 2

The result should be product 4, as this is the second in the list of products filter

[SteveCampbell]

Measure = 
var _selected_invent_spot = min('Inventory Spot'[Inventory Spot])

return
CALCULATE(MAX(inventory[inventory item]),
    FILTER(
        ADDCOLUMNS(VALUES(inventory[inventory item]),"AAA", RANKX(ALLSELECTED(inventory),inventory[inventory item],,asc) )
        ,[AAA]=_selected_invent_spot))

So my issue was FIRSTNONBLANK

[SteveCampbell]

Both solutions work, the selected answer is cleaner

Hi @SteveCampbell,

Can you share a sample and the expected result? Especially the data structure. Please check out the demo in the attachment.

Measure =
VAR whichOne =
    SELECTEDVALUE ( selectedProducts[Selected] )
RETURN
    MAXX (
        FILTER (
            SUMMARIZE (
                'Products',
                Products[ProductName],
                "ranks", RANKX (
                    ALLSELECTED ( 'Products' ),
                    CALCULATE ( SUM ( Products[ProductID] ) ),
                    ,
                    ASC
                )
            ),
            [ranks] = whichOne
        ),
        [ProductName]
    )

Best Regards,

Measure = 
var _selected_product = FIRSTNONBLANK('Product Spot'[ProductSpot],99)
var _invent_prod_rank = CALCULATE(RANKX(ALLSELECTED(prods),FIRSTNONBLANK(prods[prod item],1),,ASC))
var _selected_item_table = 
FILTER(ADDCOLUMNS(VALUES(prods[prod item]) "AA", _invent_prod_rank )
    ,[AA]=_selected_product)

was where I was going, which works but only with prod item row context
