If the above error message appears when you attempt to save an expense report, this is because the expense calendar for the current expense year hasn't been configured.
To do this, follow the steps below in back office.
Click CoreExpense, then click Reference.
Click Reference D-L, then click Expense Calendar.
To add an expense start and end year, click the add
icon.
In the Company Code field, enter the company code.
In the Expense Start Year and Expense End Year fields, enter dates for the current year.
Click the save
icon.
If you've configured the expense calendar and the issue persists, check that the claimant is not attempting to save the expense report with dates spanning across another expense calendar year, as the system will not allow this.
📌 Note: If you run into another error such as Mileage seems to be spanning the expense year, you need to configure the current mileage calendar for the expense year.
