Are there custom menus installed for this layout?
A custom menu is installed on the layout based on the privilege set. I am logged in as the administrator so the default FM menu is installed. It seems to be related to the portal. If I take the container field out of the portal and place it somewhere else on the layout, the insert pdf option is available. Once I put it back into the portal the option is grayed out.
It was the portal.
FM help states "You cannot work interactively with container fields that are in portals."
