    use "try....otherwise".

     

    try <some code hear that may result in an error> otherwise  <run this code in case of error>

     

    note that try and otherwise are NOT capitalized.  Also, no commas are needed.

    Hi all,

    unfortunately this doesn't solve my issue.

    1. There's a textfield, with e.g. 01.02.2019 - 28.02.2019
    2. I divide this column into column A (startdate): 01.02.2019 and column B (enddate): 28.02.2019
    3. Now it can happen, that there is 01.02.2019 - 30.02.2019 written
    4. Due 30.02.2019 definitively an error occurs

    If something like (4) happens, in column B must be written 31.12.2030 (e.g) and in a third column "check supplydate".

     

    How can I fix this?

    Maybe iferror / try.....otherwise is the wrong idea?

     

    Thx in advance for your help.

      let
          Source = Table.FromList({[TextField ="02.01.2019 - 02.28.2019"],[TextField ="02.01.2019 - 02.30.2019"]},Record.FieldValues, {"TextField"}),
          #"Added StartDate" = Table.AddColumn(Source, "StartDate", each try Date.FromText(Text.BeforeDelimiter([TextField], " ")) otherwise Date.FromText("12/31/2030")),
          #"Added EndDate" = Table.AddColumn(#"Added StartDate", "EndDate", each try Date.FromText(Text.AfterDelimiter([TextField], " ", 1)) otherwise Date.FromText("12/31/2030")),
          #"Added Action" = Table.AddColumn(#"Added EndDate", "Action", each if [StartDate] = Date.FromText("12/31/2030") or [EndDate] = Date.FromText("12/31/2030") then "check supplydate" else "")
      in
          #"Added Action"
