I am receiving the following error when executing an update method:

SmartObject property CreatedDate is a required property for selected method UpdateOrderTerms. Value must be set.

I am reading a record from the database with a smart object, and then attempting to update the record after changing some of the values.  The data is successfully read from the database and stored in a data field in the process, but when the update method is called, I get the error.  Anyone have this same error or know how to fix it?

Thanks in advance
