What is a requirement for the custom fiscal year setting?

A requirement for the custom fiscal year setting is that it must be defined manually. This entails that a user or administrator needs to specify the start and end dates for the fiscal year according to the organization's specific accounting or operational requirements. Unlike the standard fiscal year, where predefined settings are in place, manual definition allows for flexibility and customization based on the unique calendar needs of the organization.

The other options discuss attributes of the custom fiscal year but do not reflect the fundamental requirement of how it is set up. For example, while certain features may adapt depending on fiscal year settings, the manual definition denotes a crucial step in establishing a fiscal calendar relevant to specific business practices. Disabling or changing the fiscal year setting is often subject to rules and can have implications across the organization's financial planning, which reinforces the need for careful manual setup at the outset. Hence, manual definition is a requirement that emphasizes the tailored approach organizations may need when configuring their fiscal year.
