Go to SPRO>>>IMG>>>Sales & Distribution>>>Billing>>>Billing Documents>>>Country-specific features>>>Maintain Maximum No. Of Billing Items.

You must also go to copying control for order/delivery to billing document at item level under "Data VBRK/VBRP" and maintain routine 006 "individual invoice limited" or a similar routine that accesses the data maintained here.
