## Narrative

**Business context:** 采购管理 → 物料采购流程 → 采购发票 — post-save validator on `purpurchaseinvoicemaster`. After the user clicks save, this hook fires before the result is returned, but its real work is to delegate to the after-save calculator: it is a thin pass-through wrapper around `Sp_afterSave_sPiv`.

**What it does:** Initialises `sCode=1`, defaults `iFlag` to 0, clears `sReturn`, opens a `top:` block, and immediately calls `Sp_afterSave_sPiv(sGuid, sBrId, sSuId, sCode, sReturn)`. No table touch or validation logic of its own — the entire enforcement lives in the peer after-save proc.

**Invocation:** Bound to `gdsmodule.sSaveProName` on `采购发票` (`19211681019715782883617940`). Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. Pre-save peer is `Sp_beforeSave_sPiv` (bound on `sSaveProNameBefore`). xly-src has no install script for this exact stub — only the peers ship under `script/标版/30100101/`.
