I have created a Task record type and a page layout for it. A process builder is invoked that then creates a task record. Question is, somehow the task Standard field 'Description' is not available in page layout pallette to place in my page layout. However, in my process, I am able to set value of description. Adding to this, somehow Description field is not available in setup. I have to see it in workbench! Yes, I am a system administrator and I have checked permissions (R,E). Am I missing something? Any help? Thanks in advance.
