Why can't I close a fiscal period?
Required checklist items and the period's status control close readiness.
You need Manage fiscal periods (close/reopen/lock) permission. The period must be open and every required checklist item must be completed. Read Close Readiness for blockers and warnings. Draft or unbalanced transactions create warnings in this check; they do not automatically block closing. Completing a checklist item records your confirmation and does not perform the named task. Follow Close a month and Use period close checklists.
