Field help (IMESVIC) 

You can specify how scheduled invoices must be grouped when generating invoices:

1 invoice by invoice date

All scheduled invoices where the next invoice date is the same are grouped on a single invoice.

1 invoice by order

All scheduled invoices linked to the same order and where the next invoice date is prior to the invoice date are grouped on a single invoice.

1 invoice by customer

All scheduled invoices of all orders processed for the same bill-to customer and where the next invoice date is prior to the invoice date are grouped on a single invoice.

1 invoice by project

All scheduled invoices linked to the same project code where the next invoice date is prior to the invoice date are grouped on a single invoice.

SEEINFO The grouping criteria are implicitly based on thePJTSNGDOC - One project by document parameter (TC chapter, MIS group). When this parameter is set to Yes, grouping scheduled invoices linked to orders with a different project code is prohibited.
