This error occurs when a customization or event subscriber modifies the filter on the "No. Series Code" in a way that causes inconsistency or an invalid state. Specifically, the error suggests that the event subscriber handling the "No. Series" is altering the filter incorrectly or leaving it empty, which violates the expected behavior in Business Central. We Recommend Contact your development partner or internal team if you cannot identify or resolve the issue. They may need to audit the event subscriber logic or provide updated code. If this is a system error without customizations, consider raising it with Microsoft support or your Business Central partner.
