## Lookup value from another table based on conditions

I need a help writing a DAX function that retrieves a value from table2 based on Lane column (Tables have no active relationship). The function should compare the ShipDate from Table1 to the LastUpdatedDate from table2. If the ShipDate is greater than or equal to the LastUpdatedDate, the function should retrieve the ShippingDays values from the most recent LastUpdatedDate. Here is an example screenshot.

Any help will be appreciated!

Hi,

Please check the below picture and the attached pbix file.

It is for creating a new column in the Table1

``````ShippingDays CC =
VAR _lane = Table1[Lane]
VAR _date = Table1[ShipDate]
VAR _fromothertable =
INDEX (
1,
SUMMARIZE (
FILTER ( Table2, Table2[Lane] = _lane && Table2[LastUpdateDate] <= _date ),
Table2[LastUpdateDate],
Table2[ShippingDays]
),
ORDERBY ( Table2[LastUpdateDate], DESC )
)
RETURN
MAXX ( _fromothertable, Table2[ShippingDays] )
``````
