it works fine when I save to Excel, however when I save to Pdf, the Author property is empty. Is it normal? If Yes, does that mean I have to post-process the pdf file? [open, set the property and save] ?
The feature (exporting document properties in the pdf file) is not available at the moment. I have logged your feature request int our tracking system with an id: CELLSNET-17821, We will soon look into it.
