User has set a custom invoice numbering for projects using the Projects > Billing Options screen. However, on trying to bill the project in the Create Batch Invoice screen, user gets the following error:
Cannot perform the action as the value is too large to fit.
This can happen if you are using a custom invoice number with the Last Invoice # field having more than 10 digits. You should either use less than 10 digits or you can use the Prefix and Suffix fields to hold some of the digits or characters. Check CORE Help Center for details.
