Billing with large no of line items

Hi Experts

We are implementing sap for some European countries (France, Sweden, Belgium) specifically and have plants abroad enabled. We have invoices which have high number of line items and they cannot be split to become limitation of 999 line items. Every time we have such invoices they fail since the number of line items is huge. Is there a way out in which these could be overcome and also be compliant with reporting requirements like intrastat. Please advise.

Regards

Gauri
