1. On the General tab of the allocation, confirm the Pool selected
2. On the Source/Destination tab, scan through the rows to note all entries where the source is in one fund and the destination account is in a different fund (this would need to be repeated multiple times if there are multiple income or expense types)
3. At the top of the page, confirm the interfund set selected
4. Add any missing combinations to the Interfund set in Configuration
5. Run the pre-allocation report again to confirm all necessary interfund entries are now available to the allocation.
