Filter List of Numeric Values from other Table

Hi, Harvey85 

Based on your description, I have created the following sample data:

Table_1:

Table_2:

Labor_Table:

The relationship between the tables is as follows:

I'm using the following DAX to filter the rows with Valid = Yes:

End_Date =
VAR _mediumtable =
    SUMMARIZE (
        FILTER ( 'Labor_Table', 'Labor_Table'[Valid] = "Yes" ),
        'Labor_Table'[Labor_Id],
        'Labor_Table'[Labor],
        'Labor_Table'[Valid]
    )
RETURN
    MAXX (
        FILTER (
            'Table_2',
            'Table_1'[Key_Campaign] = 'Table_2'[Key_Campaign]
                && CONTAINSSTRING ( 'Table_2'[catstock], "SEA." )
                && 'Table_2'[Labor_Id] = [Labor_Id]
        ),
        'Table_2'[save_date]
    )

In the variables, I use FILTER to filter out the rows with Valid=Yes. And use the summarize function to summarize, the main purpose is to get the corresponding row name so that this column can be used in MAXX.
The DAX execution result is as follows:

I've provided the PBIX file for this time below, and it would be great if it would help you.
