How can I use partial receipts?

Use the AutoCash rule set Apply partial receipts option with the Apply to the Oldest Invoice First rule. Enabling this option lets you apply a receipt to a transaction with an amount less than the amount required to close the debit item.

If the AutoCash rule set doesn't use partial receipts but does include late charges in the open balance calculation, then Receivables can interpret a receipt application against a transaction amount plus late charges as a partial receipt.

For example, you intend to close a $100 transaction by applying a $100 receipt, but the transaction has since accumulated a $10 late charge. If the Apply partial receipts option isn't enabled, Receivables can't apply the $100 receipt to the new $110 open debit item.
