Invoice on returns

hi,

i have doubt regarding invoice

for example i have created a salesorder to a customer for 10 items. and i was created the delivery for 10 items and created invoice for 10 items and send it to customer. but while receivig the goods at customer place customer found that 2 items damaged out of 10 .so he received 8 items only .that means customer returns 2 items back .

1. again we need to create invoice?

2 .if we create the invoice wht about previous invoice. how sap will handle these things?

3.can u pls tell me the invoice procedure in sap ?

regards

Guru
