CRE 300 allows applying the initial cash receipt (through Enter Cash Receipts) to the distribution level of an invoice BUT if you have a Customer Cash Receipt and at a later date are ready to apply, CRE 300 does not allow us to apply to the distribution, only to the invoice.  In contacting support, they have NO workaround and no indication as to when this could be incorporated in an update.  Does anyone out there have a workaround????
