Find the invoice batch. See: Finding Invoice Batches. In the Invoice Batches window you can do the following:
Modify batch invoice defaults. Invoice batch defaults you enter in the Invoice Batches window apply to invoices you enter after entering or changing an invoice batch default. For example, if half of the invoices you are entering are standard and half are credit memos, after you have entered all standard invoices, you can change the Type default to Credit Memo so you will not need to enter Type for each credit memo.
To change a field for an invoice you have already entered, you must make the change directly to the invoice in the Invoices window. See: Adjusting Invoices.
Modify Control Count and Control Total. If you find a duplicate invoice when entering a batch, you may want to throw it away and adjust the control count on your batch. Payables allows you to change the control count or control total at any time before creating journal entries.
Add invoices to a batch. You can add invoices to a batch at any time.
Delete invoices from a batch. You can delete an invoice from a batch at any time before the invoice has been validated.
Save your work.
You cannot delete an invoice batch that contains invoices. If you want to delete an invoice batch, you must delete the invoices in the batch.
