This is where you can define a maximum number of items allowed for all billing documents within a given sales organization.
A Brazilian sales organization can currently print no more than 98 items per billing document.
Maintaining data here is not enough alone to bring about a billing split by number 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.
