If Billing, Check Writing, or Cash Receipts is blocked by Error 5093 when posting 2026 dates (period 202601), I provide a guided remote remediation process for this E2 v7 issue.
Error Code: 5093
Error Message: "Invalid Period Number"
Calling Module: CheckDet.FRM:cmdOK_Click
In typical configurations, the period is represented as 6 digits in the following format: YYYYMM, where YYYY is the four-digit year and MM is the month 01-12.
Example: 199610 would indicate October, 1996
Problem: When attempting to post 202601 (January 2026), E2 v7 rejects the period as invalid, blocking all accounting workflows.
If you see this exact error when posting 2026 dates, this fix applies to your system.
