Credit Memos for Expense Report??

Hi there

We have been raising credit memos for expense reports by matching the credit memo using the corrections screen on 12.1.3, (as quick credits isn't possible for expense report), however this has now stopped as it appears the correction screen can only be used for standard and mixed invoices (not expense reports)

i was wondering if there is a way to match a credit memo to an expense report, or if it is only possible to do this by manually creating the credit memo

Regards

Dan
