Run Python Script from Model Builder outside Arcmap

I have created a model builder that appends a Query Layer (view) in the SDE to an existing featureclass an this process works
in Arcmap fine. However when I run the script out side arcmap I receive the following error:
ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000338: Inputs must be either all Feature Classes, Tables or Rasters; not mixed.
Failed to execute (Append)
Any Suggestions or workarounds to have this run outside Arcmap?
