If you want to distribute an in-company update that is bundled with a PDF Document you may easily attach a PDF Attachment to your Social Wall Post.
When editing or posting something new for the Social Wall toggle the Add PDF Attachment option. Now upload your PDF document and give it an employee-friendly name. This name will be shown on the button that leads employees to the actual document.
The PDF will open up from within the Harry HR application and so it will not be downloaded by your employees. This makes sure your in-company PDF documents will not be floating around and makes it easy for your workers to open up and read the document.
