Depends on what you mean by partial prepayment? :-)
If multiple prepayment invoices posted for sales order and the you'd like to create a credit memo for one of those, unfortunately this can't be done in W1. Posting Prepayment Credit Memos post a creadit memo for ALL prepayment invoices.
However, PL (Polish) version of NAV 2009 R2 has this posibility implemented. It works in a way that it will ask you for which prepayment invoice you'd like to post prepayment credit memo and then post correction only for it.
Another workaround is to create standard creadit memo and enter G/L account Type line with Account No = Sales Prepayment Account (you've set on GL Posting Setup) and post it. It will correct a particular invoice then, but original sales order then won't be aware you've posted a credit memo for prepayment.
