Filter what data is imported by date

Hello all, I have a progress database connected via ODBC. I have a large table called diary with many rows and I want to speed up the time it takes to refresh this table. I have searched high and low on the forums for an answer and probably have come across the answer but due to my lack of knowledge not understood it but how do I bring less rows into power bi? I want to use the column dd-date to restrict to current month and anything in the future if possible. here is the code from the advance editor of 1 dashboard I am building

let
Source = Odbc.DataSource("dsn=moveware", [HierarchicalNavigation=true]),
MOVEWARE_Database = Source{[Name="MOVEWARE",Kind="Database"]}[Data],
PUB_Schema = MOVEWARE_Database{[Name="PUB",Kind="Schema"]}[Data],
diary_Table = PUB_Schema{[Name="diary",Kind="Table"]}[Data],
#"Changed Type" = Table.TransformColumnTypes(diary_Table,{{"dd-time", type time}}),
#"Duplicated Column" = Table.DuplicateColumn(#"Changed Type", "dd-date", "dd-date - Copy"),
#"Duplicated Column1" = Table.DuplicateColumn(#"Duplicated Column", "dd-time", "dd-time - Copy"),
#"Merged Columns" = Table.CombineColumns(Table.TransformColumnTypes(#"Duplicated Column1", {{"dd-date - Copy", type text}, {"dd-time - Copy", type text}}, "en-GB"),{"dd-date - Copy", "dd-time - Copy"},Combiner.CombineTextByDelimiter(" ", QuoteStyle.None),"datetime"),
#"Changed Type1" = Table.TransformColumnTypes(#"Merged Columns",{{"datetime", type datetime}}),
#"Removed Other Columns" = Table.SelectColumns(#"Changed Type1",{"dd-date", "dd-type", "ddID", "dd-brch", "rpid", "dd-desc", "dd-vehicles-act", "dd-labour-act", "dd-cancelled", "datetime"})

#"Removed Other Columns"
