There is an invoice posted to a accounting code segment value that was disabled (still the combination is enabled). The segment value 'cost center' was disabled a month ago and invoice have been created using the same value after that.
How to resolve the issue?
Date ending a code segment value renders it unusable in Journals where the effective date is after that date (journals for future enterable periods have an effective date of the 1st of the month while journals in the current period have an effective date of today or the last day of the month. Any new combinations which contain a date ended segment created by dynamic insert, up until the end date, will have the same end date. Earlier combinations are not affected. You can date disable with DEC-17 and still post in Nov-17
