One Time Payment doesn't have a front end only FBDI. So we cannot capture supporting documentation & approvals. Does anyone else has this requirement? How are you handling the workflow outside of Oracle? Have you heard of any enhancements coming in this regard?

We're looking for something similar to Expenses wherein users can attach supporting documentation, route it for approvals and then finally process it into an invoice.
