Calling AIF Sales Order Web Service Error: SalesOrder invalid child element!

When you call the out-of-the-box AIF Sales Order Web Service, you might face a very strange and non-understandable error message saying:

The request failed with the following error: The element ‘SalesTable’ in namespace’http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder’ has invalid child element ‘QuotationId’ in namespace’http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder’.

If you faced this, and looked for a solution you might have gone to Dianne Siebold’s WebLog:http://blogs.msdn.com/dsiebold/archive/2010/01/21/request-failed-error-in-aif.aspx. Honestly, in the beginning I did not get what she said. Then when I got what she is trying to say, I did not like it , with all my respect to her of course.

Now when you dig in the XSD generated from the Sales Order Service, you would notice that the field Customer requisition (PurchOrderFormNum) is mandatory… you have to include it in your message. This is what this “unclear” message is all about.

But the question that might cross to your mind is why I should include such field in my Sales Order although I can create new sales order in the Dynamics AX Sales Order Details form with filling this field.

This is what I will explain in my next post .
