Data Match and Selection

[PioneerZhu]

Thank you upfront.

I have 2 tables already imported into PBI as below, wonder how to create a view to filter out records from Table 2 based on Table 1 that only with Direct Flight Avaliable? As a result, only the red line show up. 

Table 1:

Direct Flight List
From	To
Dallas	New York
Austin	Seattle

Table 2:

Planned Trip List
Name	Month	From	To
Tom	Feb	Houston	New York
Frank	March	Dallas	New York
Nate	August	Austin	New York

Hi @PioneerZhu 

If you want to do this from Dax side please follow the following steps 

click on modeling new table 

copy and past the following code to create a Dax calculated table

FilteredTrips = 
FILTER(
    'Planned Trip List',
    LOOKUPVALUE(
        'Direct Flight List'[To], 
        'Direct Flight List'[From], 'Planned Trip List'[From], 
        'Direct Flight List'[To], 'Planned Trip List'[To]
    ) <> BLANK()
)

you can see the table on the Table view

Hi,

In Power Query, you can merge table 1 into table 2 based on 2 columns - From and To.  Thereafter just apply a filter.

Add a table visual with table 2 fields. Then add the following measure to the filter pane and filter not is blank.

var trip = SUMMARIZE( table2, table2[from], table2[to] )
var matchingFlight =
   CALCULATETABLE(
      table1,
      TREATAS( trip, table1[from], table2[to] )
   )
return
IF( NOT ISEMPTY( matchingFlight ), 1 )
