We are wanting to add a retention policy for a site that holds academic material. The retention will be current year plus 5, this is not calendar year. So if a document was created on september 2009 or january 2010 they both would have the date of july 2010 + 5 years for when they should be removed. I could handle this by having a workflow that runs whenever a document is created that calculates the end of year date and then apply the +5years via the retention rule. Is there a better or simpler way of handling this? Specifically calculating the end of year date so I can use a normal retention policy on this.
Thanks
