missing columns not returned when iterate through ...

cleon169 · ‎05-03-2018

I'm calling a SOAP API in XML to pull down a report into Power Query. The query iterates through a list of locations stored in a manual table. The problem I have is when the location doesn't have a value for a column, it doesn't return the column at all. This is resulting in the power query erroring out when it can't find the column. I'm assuming I need to define the elements using something like an element path, but I'm clueless on how to do that in the XML. Can anyone help please?

For example, I'm getting this error:

An error occurred in the ‘’ query. Expression.Error: The column 'MoveIn' of the table wasn't found.
Details:
    MoveIn

Here's the query:

(AllLocations) as table =>

let

MTDBegin = DateTime.ToText(Date.StartOfMonth(DateTime.LocalNow()), "yyyy-MM-ddT00:00:00"),
MTDEnd = DateTime.ToText(DateTime.LocalNow(), "yyyy-MM-ddThh:mm:ss"),

    Source = Xml.Tables(Web.Contents("https://.../...Ws.asmx?WSDL"

    ,[Content=Text.ToBinary("<soapenv:Envelope xmlns:soapenv="&Character.FromNumber(34)&"http://schemas.xmlsoap.org/soap/envelope/"&Character.FromNumber(34)&" xmlns:rep="&Character.FromNumber(34)&"http:/.../ReportingWs"&Character.FromNumber(34)&">

@cleon169,

I note that the #"Changed Type" step metions the 'MoveIn' column. When your table doesn't have this column, the above error will throw. Please delete the "Change Type" step under "APPLED STEPS" in Query Editor of Power BI Desktop.
