Why is it that the Report can show Template Field meta data for 'Created Date' and 'Created By Name' and yet these aren't available in the workflow to export to excel? These exist in the data so why am I not able to reference in my workflow?

All meta data is important information. Knowing who the original creator of a form was is more important to me than who took ownership or edited the record.

I believe that all form fields and meta data fields should be accessible in workflows, for filtering or in exporting the data to other applications (ie Excel).
