I have a customer like "Customer A'
earlier the said customer has Debt-LMT-KHI account mapped as Receivable Account
later on we have changed is AR account from Debt-LMT-KHI to Debt-LMT-IMS,
now we are not able to knock off old invoices which has Debt-LMT-KHI account with payments made under Debt-LMT-IMS
Anyone has any idea how we handle this situation so that customer's old invoices will be knock off and aging report would be ok?
