Need an Invoice Copy

Hi All,

Our Customer needs an invoice copy for already billed document. I checked the output in VF03 but no output has been maintained for it. Even in the delivery document no Output has been triggered.No Output Condition record also exists for this.

So how can we generate an invoice copy for already Billed document?

Even for proforma invoice it is necessary to maintain output determination procedure?

Is there any way to generate invoice copy for this billing document?

Thanks in advance,

Regards,
