RemarksThis function is like DbCreateOrder() but strongly typed and the condition information is passed in an object.
This function, however, does not call the error handler and will therefore not produce a runtime error message or create an error object if it fails.
Therefore it is important to check the return value to determine if the function succeeded.
The LastRddError property in the runtimestate will contain needed information about any error that occurs.
