The narrative above explains; the sections below are authoritative — the rules, scenarios and tests this document binds.
| # | Surface | Action | Capability | Expected | Provenance |
|---|---|---|---|---|---|
| 1 | /console/{tenantId}/configuration/accounting/businessUnits | Attempt to choose CAD on the saved unit. | CAP-ACC-BKS-001 | Founding fields are fixed in the editor and a forced change receives a field-specific refusal. | test |
| 2 | /console/{tenantId}/configuration/accounting/businessUnits | Request deletion of the mistaken unit. | CAP-ACC-BKS-001 | The refusal identifies its GL account and project. | test |
| 3 | /console/{tenantId}/configuration/accounting/glAccounts | Remove the unit’s GL account and accounting project. | CAP-ACC-BKS-005 | Both dependent records are deleted. | test |
| 4 | /console/{tenantId}/configuration/accounting/businessUnits | Retry unit removal. | CAP-ACC-BKS-001 | The unit, owned departments and fiscal calendar are removed. | test |
| 5 | /console/{tenantId}/configuration/accounting/businessUnits | Create a CAD replacement using the previous identifier and an April start. | CAP-ACC-BKS-001 | A new April-based 2026–2027 and 2027–2028 calendar is created. | test |
| Path | From step | Condition | Path taken | Outcome | Provenance |
|---|---|---|---|---|---|
| failure | 4 | A product setup still uses a department of the unit. | The refusal identifies product usage. | The unit and department remain saved. | test services-accounting:modules/books/tests/integration/services/persistence/departments.integration.spec.js#refuses the delete 409, naming the unit’s products |
| Id | Statement | Provenance |
|---|---|---|
01 | Editing does not alter a saved unit’s base currency. | test services-accounting:modules/books/tests/e2e/business-units.e2e.spec.js#answers 409 to a change of the base currency, naming the column |
02 | Account and project dependencies prevent removal until cleared, after which owned setup is removed. | test services-accounting:modules/books/tests/integration/services/persistence/business-units.integration.spec.js#leaves no fiscal year, fiscal period or department of the unit behind |
03 | Reusing the unit identifier creates a new initial fiscal calendar. | test |
End-to-end policy: required: The correction spans immutable choices, dependency refusals and cleanup across several editors.
