calculated column

[murillocosta]

Hi,

Could someone help me achieve the below.

I have a table which I need to find the max period_id per per facility_id like the example below 425 to facility 1 and 424 to facility 4.

Once I figure this value out I need to get another column value (exchange_rate) and repeat it to the others rows for that facility_id as shown below.

I can't use power Query as I need to dynamically change this table when the main date slicer is changed

Tks

apparently tamerj1's solution worked perfectly and more elegant, but this might be easier to digest:

result2 = 
VAR _facility = [FACILITY_ID]
VAR _period = 
MAXX(
    FILTER(
        Table01,
        Table01[FACILITY_ID] = _facility
    ),
    Table01[PERIOD_ID]
)
RETURN
MINX(
    FILTER(
        Table01,
        Table01[FACILITY_ID]=_facility&&Table01[PERIOD_ID] = _period
    ),
    Table01[EXCHANGE_RATE]
)

Thanks guys that's really helpfull.

The only thing I forgot to mention is that I also to need to filter the MAX date selected from my calendar table on the slice.

Like in the example below I selected 31/10/2021 which is period 400 for subsidiary 1, but the measure is bringing 426 which is the highest period on the overall table.

Any idea the best whey to apply this calendar date filter?

Thanks

To avoid double scan of the table you can use

result2 =
VAR _facility = [FACILITY_ID]
VAR T =
FILTER ( Table01, Table01[FACILITY_ID] = _facility )
VAR _period =
MAXX ( T, Table01[PERIOD_ID] )
RETURN
MINX ( FILTER ( T, Table01[PERIOD_ID] = _period ), Table01[EXCHANGE_RATE] )

Hi @tamerj1 

Thank you very much. That is a good use of table variable. I actually have such double scans very often. It is very insightful. Learned a lot from you.

Hi @murillocosta 

please try

NewColumn =
MAXX (
TOPN (
1,
CALCULATETABLE ( Table01, ALLEXCEPT ( Table01, Table01[FACILITY_ID] ) ),
Table01[PERIOD_ID]
),
Table01[EXCHANGE_RATE]
)
