RE: Apply posted credit memo to a different customer's invoice
You can't do this directly. What you can do, is to transfer the amount from one customer to another first, and then apply it. For this, you need to e.g. in the financial journal, enter two lines with account no. but without balancing account no:
- first line you will create an invoice for the customer #00001
- second line is a credit-memo for customer #00002
then, apply invoices to credit-memos in both customer ledger entries
Alternatively, you can create invoice for customer #00001 and apply it to credit-memo; then, create new credit-memo already for customer #00002 and also apply it.
