 4. Shows the remaining amount for partially reconciled payments
 
+### Grouping and Aggregation
+1. In the payment list view, use the **Group By** filter (e.g., by **Partner** or **Journal**)
+2. The group headers will display the total sum of the residual amounts for each group
+3. The bottom of the list view displays the total residual for all visible records
