We do not support “editing” of member opening balances. You have following options to ‘rectify’ the incorrect entries:
For incorrect dues –
(a) Issue a credit note to members where excess dues were entered and raise new invoices where less dues were entered.
(b) Revert the opening balance by going to Income->View Charges and the upload the correct dues again.
For incorrect advance payments, you have to delete the payments by going to Income->View Payments and upload the correct advance amounts again.
It is important to be in the correct accounting period when doing the above.
