The Document subject property allows you to define a subject or a subject pattern for your template. If you only set a document name, the document name will be set as subject as well. So when you use the [Create Activity]-button form the Client, the subject will be already prefilled in the creation dialog.
Please note: This setting only affects the DocumentsCorePack Client Based process!

Example: A template named Quote_Base.docx (1) populates the subject field of the Create Activity dialog Nuclear Power Plant-QUO-01000-W4G3T9.docx (2).

   DocumentsCorePack client in order to publish the template to Dynamics 365.
