I created a Sales Order for 2 quantities and posted it. The Customer Ledger Entry created for the invoice is Open, and the Closed at Date field is blank, as expected.
Then I created a Sales Credit Memo against the same invoice for the full 2 quantities and posted it. After posting, the Closed at Date is populated for the invoice’s customer ledger entry, but it is blank for the credit memo entry.
Is this expected behavior or something unusual?
