Replace dates less than specific date to NULL

Hi,

 

My date column contains a range of dates. I need to replace dates prior to Jan 1, 2007 with null. I've got this:

 

= Table.ReplaceValue(#"Filtered Rows1",each [Mfg Date] < #date(2007, 1, 1),null,Replacer.ReplaceValue,{"Mfg Date"})

 

But no effect.  Help would be appreciated. Thanks.

This seems to work in my small sample as a Custom Column:

if Date.Year([Date]) < 2007 then Replacer.ReplaceValue([Date],[Date],null) else [Date]

However I believe this is what you're looking for:

= Table.ReplaceValue(Source, each[Date], each if Date.Year(Date.From([Date])) < 2007 then null else [Date], Replacer.ReplaceValue, {"Date"})

You'll have to play with the Date.Year(Date.From([Date])) as I do not know what your current data type is.
