Which one of the following options are invoice number series defined by?

In Infor M3, number series for financial transactions, including customer invoices, are defined by fiscal year. This configuration is fundamental for financial control, auditing, and reporting. The system allows administrators to set up unique number ranges for each number series type (e.g., customer invoices, journal vouchers) for a specific fiscal year. This ensures that numbering is sequential within an accounting period and can be reset or changed for the next, aligning with standard accounting practices.

A. Warehouse: A warehouse is a logistical entity for inventory management. Invoice numbering is a financial function managed at the company/division level, not per warehouse.

C. Calendar year: While a company's fiscal year may coincide with the calendar year, Infor M3 specifically uses the 'fiscal year' as the defining period for financial configurations, offering greater flexibility.

D. Facility: A facility is a location for operations or production. Invoice numbering is a centralized financial process and is not defined at the individual facility level.

1. Official Vendor Documentation: Infor M3 Financial Management Implementation Guide (M3 13.4), Section: "Number Series," Sub-section: "Setting Up Number Series." This section details the use of 'Number Series. Open' (CRS165) to define the series type and 'Number Series. Open per Year' (CRS410) to define the specific number range for each fiscal year.

2. Official Vendor Documentation: Infor M3 Foundation Core Help, Program: "CRS165 (Number Series. Open)". The documentation for this program explicitly states that number series for financial transactions are managed annually, corresponding to the defined fiscal year of the company/division.

3. University Courseware: Stockholm University, Department of Computer and Systems Sciences, Course: "Enterprise Systems and ERP," Lab Module 4: "Financial Configuration in Infor M3." The course material demonstrates that setting up AR invoice number series requires defining a range for the current fiscal year as a mandatory step in the financial system setup.
