Partial Payment- need clarification on 2 scenarios

Hello SAP Gurus',

I need some help. If I check the Partial Payment in the Control Parameters node in Bank transactions, what does it mean? I thought it meant that if a payment came in and referenced that invoice, it would clear that invoice leaving residual on account where applicable.

Through Lockbox postprocessing via FLB2, if the user decides to use the partial payment tab and leaves a difference there, it would leave the invoice open and a new line item would be created in open items indicating and overpayment or shortage. Is this correct.

Many thanks!
