I've got a batch of files that were provided to me by a client. For various reasons, I need them combined into one, multi-page file that allows me to add a footer. These files all contain form fields that when merged into one file get lost. Combining them as a package has other complications (can't add footers, etc.). I've tried to create an action that contains a preflight process to flatten annotation & form fields but it errors out because the document restricts some DC features to allow for extended features on Acrobat Reader.
However, if I run preflight as individual files and save them out individually, it works fine. I'd be willing to do this, but I've got over a hundred files to process on a weekly basis.
Why does the file error out when processed as an action, but executes fine when processed individually?
