Original receipts can be disposed of/destroyed once the expense posts in the financial system. This will align OSP with University policy on record retention and is allowable by sponsors. Since the electronic document/digital image is the back-up record for auditing purposes and is stored in the University controlled and secured financial system, it can be retained for an infinite period of time.
For example: if a project requires documents be retained for 10 years after end of a project, then the electronic image will not be purged from the system until after the 10-year period has elapsed.
