The doc explains that there is an interaction between the PDFSECURITY option and this option. But, I don't think just using the options is going to work for you. Part of having forms in a PDF file is that you have to use Adobe to define the form fields.
I can create a file using the above options, however, when I open the file with Adobe Acrobat, there are no form fields defined. (I can choose Forms --> Add or Edit Fields, but, I get a message that says:
"Currently there are no form fields in this PDF. Do you want Acrobat to detect form fields for you.")
So, I do not know whether there is a way to tell Adobe --from the SAS end -- which columns in the output represent form fields. You might want to check with Tech Support if this is part of your question.
