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.
