Help with Measure

[Jacobmiller23]

Hi all,

I am ccurrently working on a project in BI and am running into an issue. Basically I am trying to get a value in one table into another table based on a date and a vendor. I have been trying to use a lookupvalue function, but seem to be running into issues for some reason and keep getting an error that says "a table of multiple values was supplied where a single value was expected." Basically I have a table with every single date of 2024 and for every date there is 10 items that a price value gets entered into every day. I assumed I would be able to match the correct price by doing a lookupvalue with the name of the item and the date, but I am running into issues. 

Here is a picture of my price table to help visualize. 

Also here is an image of my error.

If anyone has any suggestions/solutions, please let me know.

Thanks!

Hi @Jacobmiller23 

Please try this:

Here I create a set of sample:

Table:

Tbale 2:

Then add a measure:

MEASURE =
VAR _currentDate =
    MAX ( 'Table 2'[Table_Date] )
VAR _currentItem =
    SELECTEDVALUE ( 'Table 2'[Table_Market Item] )
RETURN
    SUMX (
        FILTER (
            'Table',
            'Table'[Date] = _currentDate
                && 'Table'[Market Item] = _currentItem
        ),
        'Table'[Price]
    )

The result is as follow:

It's worth noting that there are no relationship between the 2 tables:
