Need Help with M Code.

[Pravin_rajput]

Hello Folks, 
I am new to powerbi and require your expertise to help me with a problem.
I am filtering out some data by defining some parameter. 
#"Filtered by date range" = Table.SelectRows(#"Change to datetime", each [WRITTEN_DATE] >= RangeStart and [WRITTEN_DATE] <= RangeEnd)
but i am also missing the values with null value in written_date field. How can i manipulate this code to get those rows in which written_date is null.

Thanks!

Hi @Pravin_rajput,

#"Filtered by date range" = Table.SelectRows(#"Change to datetime", each ([WRITTEN_DATE] >= RangeStart and [WRITTEN_DATE] <= RangeEnd) or [WRITTEN_DATE] = null)
