Which procedures did the Year End Processing screen indicate were not yet completed? Are there posting journals that need to be cleared, or the GL batch needs to be retrieved, or something else? Knowing which steps are listed as incomplete will help.

One step that we have run into a few times is that a particular posting journal was printed and cleared, but for some reason the file size of the posting journal file was not set to zero. Thus Year End still thinks that step is necessary. The solution is to manually remove the file; all posting journal files in Payables start with the letters "APPOST". If you have printed and cleared all of the journals (including the register and check reconciliation) then you can remove all files that start with APPOST. They will be recreated automatically the next time you post.

If you want to be safe, make sure you have a data backup before doing all this, though since it's year end I'm sure you already have one.
