Amicus Premium Billing has sets of restriction when it comes with the items (Time Entries, Expense) to be included on the bill. The system validates the set dates on AR Date against the Include Charges Date filter.
It is not logical to create an invoice that will include future items recorded after the an A/R date period.
- Check the AR Date filed and ensure to set the date more than or the same as the Include Charges to Date.
The AR Date cannot be a date prior to any of the transaction dates that will be included on the bill.
