Hi,

Do you want to create a single credit invoice for multiple debit invoices or credit invoices for debit invoices. Please clarify

If you want to create multiple credit invoices for debit invoices, it can be done manually through create customer credit invoices window.

Select invoice lines» Create credit invoices» Then background jobs will create multiple credit invoices.
