Multiple popup while saving invoice.

Hi Team,

While saving the invoice with different deliveries getting multiple popup's to download the invoices into PDF.

Let's say like 100 deliveries are there if we do invoice(VF01) after saving multiple popup's will raise then need to click on save button100 times to save it into PDF.

REQUIRED: Is there any solution to save it in a single click (save button) and all invoices to be downloaded at a time into PDF.

PLEASE LET ME KNOW.

Thanks,

Vamsi.
