What it does

Issue a credit note — a formal “we owe you” against an invoice.

ISSUE a CreditNote against an issued/closed Invoice: each entry addresses one invoice line with a positive magnitude (the document supplies the − sign); over-credit refuses per line STRICT (taxableBase + Σ prior signed note deltas − credit ≥ 0 → VALIDATION/INVALID naming the line); the tax delta recomputes over the line's CAPTURED components (no re-sourcing — a FULL credit mirrors the original figures EXACTLY). NO inventory movement (a goods-back is a Return). ONE transaction: the note create + the Invoice notedBaseDeltaMinor stamp under the Invoice's OCC. The org must be ACTIVE.

Careful

A money-bearing document; voiding is the only exit and is itself recorded.

Returns

CreditNote CreditNote! — A CreditNote — the REDUCING corrective document for an issued, immutable Invoice: a NEW document carrying the SIGNED delta (every figure strictly NEGATIVE — the sign lives on the document), never an edit. The tax delta recomputes over the invoice line's CAPTURED components (a correction re-prices the SAME fact, not a new sourcing) — a FULL credit mirrors the original figures EXACTLY (the sign-symmetric arms). Over-credit refuses per line STRICT (taxableBase + Σ prior signed deltas ≥ 0). NO inventory movement — a goods-back is a Return. AR effects =; fiscalization seq/sig = (named deferrals).
