Default Transaction Calendar is the calendar that you would assign to achieve the requirement of using specific business days for which the transactions should be considered in the cash positioning report. The Specify Cash Positioning and Forecast Options page is a page where you can define the options and preferences for generating and viewing the cash positioning report. You can assign a default transaction calendar to specify the business days that are used to filter and group transactions in the report. The default transaction calendar can be different from the accounting calendar or the source calendar1. References: Oracle Financials Business Process Certified Foundations Associate Rel 1
