Average only if > zero

Hi Anonymous ,

You can try to add a filter in Table.SelectRows.

List.Average(Table.SelectRows(
DaysonHandData,
(InnerTable) => InnerTable[Product] = [Product] and [Daily Average] <>0)[Daily Average])

Here I create a sample to have a test.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTJWitWBsAzgLBM4yxTMcoKLOcHVobLMlGJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Product = _t, #"Daily Average" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Product", type text}, {"Daily Average", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", 
    each 
    let _Product = [Product] in
    List.Average(
    Table.SelectRows(
    #"Changed Type",
    each _Product =[Product]and [Daily Average] <>0 )[Daily Average]))
in
    #"Added Custom"

Result is as below.
