DateAdd issue

Hi  Anonymous ,

Agree with edhans , please use EDATE() to add years.

Or you could use Date.AddYears() to a custom column in Power Query:

Date.AddYears([Date],1)

And then change its type to Date. Below is the whole M syntax:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("VczBDYAwDATBXvxGOp+tJFBL5P7bIEiA4+c8ducUUyM66BLHKyo4Cp0fDSxyuKYaemJsl5URVxH/zp9nwtF2sKdOmETc", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Date.AddYears([Date],1)),
    #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", type date}})
in
    #"Changed Type1"
