After having searched to no end I still cannot find the answer to my question....
Our current environment is an SAP and FLM system (forms livecycle management) using livecycle designer for design and all users on at least reader 9.
I would like to know if it is possible for a user to fill in a form and save the entered data (to a local file) so the following week they can then open latest version of the PDF (requested from the FLM portal to be either completed online (portal) or offline (email)) they would then import the data, make any minor updates and submit. The forms should have reader extensions applied but as yet unsure of the exact settings (if any) as this happens automatically within FLM. The form shouldn’t change in future, more than some additional validation, but allow form numbers and versions within FLM to be better maintained. Plus to ensure users do not keep or use outdated forms.
