Filter Table based on Condition from Other Table Column

You can place the following measure in the filter pane of the visual and select "is not blank" then apply the filter

FilterMeasure =
VAR InventoryLoads =
    VALUES ( 'Current Inventory'[Load] )
RETURN
    COUNTROWS (
        FILTER ( 'Container ETA', NOT ( 'Container ETA'[Load Name] IN InventoryLoads ) )
    )

Hi joshs444 ,

If you only want to get the Load Names in the table 'Container ETA' which also exist in the table 'Current Inventory', you can create a calculated column as below in the table 'Container ETA' to get it.

Column = 
CALCULATE (
    MAX ( 'Current Inventory'[LOAD] ),
    FILTER (
        'Current Inventory',
        'Current Inventory'[LOAD] = EARLIER ( 'Container ETA'[Load Name] )
    )
)

And if you want to remove the rows in the table 'Container ETA' which exist the same Load Name with the LOAD in the table 'Current Inventory', you can follow the below steps to get it in Power Query Editor...

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ldA7EsIwDATQu7jOTLSrT5wb0FBThByD+2NBkxQYp5LG8rMkb1t5mIeUqXAmZgq15bfnS4Rxb6lBkdXPnbJP/4ExgUo9guU3QIi14OcOPeAV18CKyMA4AO+AVZhvQ05L9EStkSd0GQRWLZeIhYMAwRyGtNEOCs8OdhhJ0QFOzQ8KfEfa3w==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Load Name" = _t, #"ETA to Port" = _t, Warehouse = _t, #"Weruva SKU" = _t, Quantity = _t, #"Delivery date to H&M" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Load Name", type text}, {"ETA to Port", type date}, {"Warehouse", type text}, {"Weruva SKU", Int64.Type}, {"Quantity", Int64.Type}, {"Delivery date to H&M", type text}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Load Name"}, #"Current Inventory", {"LOAD"}, "Current Inventory", JoinKind.LeftOuter),
    #"Expanded Current Inventory" = Table.ExpandTableColumn(#"Merged Queries", "Current Inventory", {"LOAD"}, {"LOAD"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded Current Inventory", each ([LOAD] = null)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"LOAD"})
in
    #"Removed Columns"

Best Regards
