Hi BBIUser ,
please try the following syntax instead:
if [Session Admin]= "Not assigned Session" then 0 else [Quantity] * (if [Date] > #date(2012,6,30) then 100 else 95)

    ImkeF Mahesh0016 Thanks for your responses!

    I get the same error and the formula did not work

    if [Session Admin]= "Not assigned Session" then 0 else [Quantity] * (if [Date] > #date(2021,6,30) then 100 else 95)

    Or

    Table.AddColumn(#"Renamed Columns", "Amount", each

    if [Session Admin]= "Not assigned Session" then 0 else [Quantity] * (if [Date] > #date(2021,6,30) then 100 else 95) --> Here the only difference between Mahesh formula and mine is I have 'Renamed columns' instead of 'Changed Type'

     

    Expression.Error: The Date operation failed because the resulting value falls outside the range of allowed values.

     

    The error says outside the range but I have data unitl 11/30/2022 and all records displays error. Below are some screenshots. Is it somethign to do with date and time format???

     

         

     

    Please let me know if you need any more info.

    Thanks!

      Hello - it looks like your date column may have varying formats.  Please try this:

      let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtc30jcyMDJUMDSyMjAAIgVHXyUdpaDM5AyF8MScktQiIM8IhIGKdA0NlWJ1opUs9Q0tsenyyy9RSCwuzkzPS01RCE4FsvLzgMKmcO1GYO1GUO1GeC21gOgy0jWAWApzAFBdflJmnkIwUGEVkGcJV2eEpM4It3PM4BqMlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, #"Session Admin" = _t, Quantity = _t, Column1 = _t]),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(Source, {{"Date", each Text.BeforeDelimiter(_, " "), type text}}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Extracted Text Before Delimiter",{{"Date", type date}, {"Quantity", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type1", "Custom", each 
if [Session Admin] = "Not assigned Session" then 0 else 
[Quantity] * ( if Date.From([Date]) > #date(2021,6,30) then 100 else 95 ) 
)
in
    #"Added Custom"

        jennratten Appreciate your response.

        May be this screenshot should help to understand more.

         

        The custom column is within a table's applied steps. So, the formula that you provided is not working in this custom column.

         

         

        Example: 

        let
    Source = Table.FromRows

        is changing to something like this with error 

        Thanks for your help!
