When creating a Customer Return the form provides the option of generating an invoice for which it generates an AR Credit Memo. The customer return document is a MM Return (base type is Material Receipt). The problem I have is that it is not possible to match a Material Receipt to a AR Credit Memo. The Adempiere Matching PO-Receipt-Invoice appears to only let you match Material Receipts to Vendor Invoices and not to Customer Invoices. At the moment I cannot match any of my Customer Return Receipts to the associated AR Credit Memos. Is this correct or am I doing something wrong here?
