Calendars
Calendars are referenced when entering general details such as payment terms and instalments for material contracts and used when generating invoices. A calendar contains the specification of which days are non-working days, or holidays. This is important when a price or interest rate is to be determined based upon a monthly average, minimum or maximum. If prices or interest rates are missing for the required date or within the date period, an error can result when the invoice is generated. Prices or interest rates can be missing if the date is defined as a non-working day.
