In certain cases, employees are granted allowance for short (less than 24hrs) travels overnight (with or without accommodation). This dialog is used to define if such allowance should be calculated in the Expense Sheet. The dialog becomes available when you save an expense sheet covering a travel time period of less than 24hrs, and also if you use Create Allowance, Create Summarized Allowance right mouse buttons.
Select the Trip Without Accommodation check-box if no accommodation was used during an overnight trip. Clear the check-box if there was accommodation but you still want to generate allowance for the short overnight trip.
