Manually create the credit memo and select some invoices so that the total amount of invoices is greater than the total amount of credits. Save this credit memo. 2. After the credit memo is saved, you can then use CSV import to update that credit memo and apply more invoices. Please note that the CSV import should contain the necessary fields to identify the credit memo and the invoices to be applied. Also, it's important to note that this process does not require any SuiteScript development. However, if you want to automate the process of applying credit memos to the oldest outstanding invoices when credit memos are loaded via CSV import, you might need to write an After Submit User Event script. This script would trigger after the CSV import and apply the credit memos to the oldest outstanding invoices.
