The first thing to check is your AD security settings on the file - does the user you are logged in have permissions. After that ensure that there is not Section Access on the file that may be stopping it showing. Another thing that can be missed it the category drop down at the top left - ensure this is set to All to view all documents.
It can sometimes help to create a new document in the same folder as the one that is not showing to see if that appears - to try and identify if it is an issue with the document or the folder permissions.
If you are using token access you will need to set the Authorization against the Document in QMC - setting the drop down to All Authenticated Users.
I am using pdf creator to generate pdf. It was working fine for me from access point. Now i am not to open qvw within the server. I cant open only this file,Others am able to open. I have full permission for this file.
Am not getting you point "Is this from the Select Report drop down menu at the top of the page in Access Point?"
When you open a QlikView document via Access Point you should see a drop down box with reports in, from which you can download PDFs. Is this working for you?
If it is from Publisher that the PDF creation is not working then it may be because the user account that you have set up for the Distribution Service does not have the rights required to access the document?
