## Narrative

**Business context:** 财务 → 凭证 — pre-delete validator for `udfVoucherMaster` (业务单据删除前校验  -1 回滚). When a user requests to delete a voucher that was generated from a business document, this proc decides whether the delete is safe and, when not, returns `sCode=-1` to roll back.

**What it does:** Looks up `udfVoucherMaster (sId=sGuid)` for `sMastertbName` (comma-separated list of source master tables) and `bMinus` (是否红冲). If `bMinus=1` the proc immediately blocks with the localised `sBusineesVoucherBillNoHcCantDel` message ("红冲凭证不能直接删除，可删除相应的蓝字单据"). Otherwise it iterates the comma-separated `sMastertbName` list, splitting each token to find a candidate update column — the disabled inner branches show the original intent was to NULL out `sVoucherBillId` on every source master row, but the executable path now just walks the list. Returns `sCode/sReturn`.

**Invocation:** Status: appears orphaned. No caller found in any channel — not bound to a form-master, no gdsmodule hook, no other routine references it, and the only xly-src hit is its own install script `script/标版/30100101/Sp_update_BusineesVoucherBillNo.sql`. The name suggests it was meant to be wired as a `sDeleteProName` hook on a voucher form but never was. Candidate for maintainer audit.
