How To Credit a Posted Contract Invoice

The procedure for crediting a posted contract invoice is the same as crediting a regular posted sales invoice. The only difference is that it is only possible to post a credit memo for the most recently (last) posted invoice in a contract. After you have credited the last posted invoice, it is possible to credit the invoice that was posted next to last and so on.

1. Choose the search icon (ALT+Q), enter Posted Sales Invoices, and then choose the related link.
2. Open the invoice you want to credit.
3. Select the Create Corrective Credit Memo action on the Posted Sales Invoice.
4. The fields Next Posting Date and Last Posting Date on the linked contract of the invoice that is credited will be updated when the Credit Memo is posted. This makes the contract ready to create documents or project planning lines for the same invoicing period (again).
