SIE import books three system entries through the engine (opening
balances, IB resynk, the omföring adjustment for excluded vouchers) —
after PR10 those passed through the rules layer, so a required rule
could block an import and default/fixed rules could inject dimensions
into derived historical entries. Year-end, currency revaluation and
credit instruments had the same exposure.
Policy now governs NEW business events only: source types in
DIMENSION_RULE_EXEMPT_SOURCE_TYPES (opening_balance, import, year_end,
storno, correction, credit_note, supplier_credit_note,
currency_revaluation, system) skip both the draft-time apply and the
commit-time assert — imported history lands verbatim (BFL 5 kap),
bokslut can never be blocked by a dimension rule, and crediting an
entry that pre-dates a rule always works. Operational sources (manual,
bank_transaction, invoice_*, supplier_* registrations/payments,
salary_payment) stay enforced.
The SIE round-trip test now also covers a PR10-created custom dimension
(#DIM 20) with a custom child (#UNDERDIM 25 ... 20) and a tagged line —
proving user-created dims survive export → parse structurally.
