/**
 * Test for issue #7864: Summary Data in Advanced Deposit Report not displaying correctly
 * 
 * This test verifies that:
 * 1. Summary Data report type displays individual fund totals (not grouped under "Undesignated")
 * 2. Each fund (General Fund, Wednesday Fund, Online Fund, etc.) appears separately
 * 3. Fund totals are correctly accumulated for each fund
 * 4. Report works correctly for all three sort types (deposit, fund, family)
 * 
 * Bug description: The Summary Data section of the Advanced Deposit Report was only showing
 * one entry labeled "Undesignated" with the entire deposit total, instead of listing each
 * fund with its corresponding total.
 * 
 * Root cause: The code was overwriting actual fund names with 'Undesignated' when fund_ID
 * was null/0, causing all fund totals to be grouped under the same key.
