Can a paid fee challan be edited — how do I delete a wrong payment, or add a remaining amount to a month that is already paid?

No — a saved payment cannot be edited directly. You delete the wrong payment on Admissions › Paid Challans, then record it again correctly. This needs the user's Delete Challan right.

Deleting a payment (wrong amount, wrong date, wrong student)

1. Open Admissions › Paid Challans and search the student (name, roll number or student number); filter to the challan month of the wrong payment
2. Tick only that payment row, press Delete Challans, and confirm
3. Return to Admissions › Pay or Print Fee Challans — the challan is back there as unpaid (or partially paid) — and receive the payment again with the correct details

The delete button on Paid Challans removes the selected payment transactions; it does not erase the challan itself. The challan becomes Fully Paid, Partially Paid or Generated again according to the payment and discount amounts that remain.

A month is paid but more should have been charged

A challan for the same month cannot be generated twice, so "generate that month again" is not the fix. Instead:

1. Delete the payment on Admissions › Paid Challans (steps above)
2. Then either:
   • add the extra on Admissions › Add Amount in Generated Challan (select the head, amount, and tick that challan), or
   • delete the challan on Admissions › Pay or Print Fee Challans, correct the student's plan on Admissions › View/Edit Fee Plans, and generate that month again
3. Receive the payment on Pay or Print Fee Challans
