## Narrative

**Business context:** 财务凭证单据 (accounting voucher) post-save validator on `udfvouchermaster`/`udfvoucherslave`. Enforces three accounting rules — (1) 费用类科目 (`sAccountNo` `6601`/`6602`) entries must have both 部门 (`sFflex5`) and 费用科目代码 (`sFflex9`) set, (2) total debit (`dDebitMoney`) must equal total credit (`dCreditMoney`) per voucher, (3) the assistant-accounting expense code (`sFflex9`) must contain the row's `sAccountNo` — then post-processes the voucher (fills 部门第三方编号, derives `sVoucherType`/`iVoucherYear`/`iVoucherMonth`/`iEntryNumber`, assigns the next `sVoucherNo`).

**What it does:** Sets `sCode=1`. Aborts (without LEAVE — the proc continues so multiple errors can accumulate the same `sReturn`) with `sExpenseNeedDepartAndCode` on expense rows missing dept/code, with `sDebitBp` on unbalanced totals, with `sFzhsNoInThis` on mismatched assistant accounts. Joins `udfvoucherslave` to `sissubject` to refresh `sFflex5` from the dept's `sThirdNo`. Defaults empty `sVoucherType` to '记'. Updates `iVoucherMonth`/`iVoucherYear` from `tVoucherDate`. Refreshes `iEntryNumber` to the actual slave row count. Calls `SP_Sis_GetMaxNo('udfVoucherMaster', ..., '15928127560001382627511178461700', ..., '{"tVoucherDate":"<now>"}', ...)` to fetch the next sequence number and applies it to empty `sVoucherNo`, also stamping `tVoucherDate=NOW()`.

**Invocation:** Status: appears orphaned. No `gdsmodule.sSaveProName`/`sSaveProNameBefore` hook on `财务凭证单据` (sId `15928127560001382627511178461700`) or any other 凭证 module in the current DB snapshot, no form-master binding, no other-routine caller, no xly-src reference. Candidate for maintainer audit on whether the 凭证 save path bypasses validators or wires this differently (the `SP_Sis_GetMaxNo` call inside hard-codes the form sId so the proc is clearly intended for that module).
