## Narrative

**Business context:** 采购管理 → 物料采购流程 → 采购退货 — post-save validator on `purpurchaserejectmaster`/`purpurchaserejectslave`. Guards two invariants: 反算 (reverse-formula) materials must have a 采购数量, and once a 红冲 (reverse-charge) record exists for the source bill, no further duplicate 红冲 is allowed.

**What it does:** Sets `sCode=1`, `iFlag=0`, clears `sReturn`. (1) Counts `purpurchaserejectslave` rows with `iHandIn=1` whose `elematerials.bInverse=0` — if any, aborts with `sCode=-8` and `sMaterialNotFsgs` ("物料不是反算公式物料，请输入采购数量进行计算") concatenated with the offending material names. (2) Reads `sMinusSrcId` from the master; if set, counts mis-matched 红冲 rows by comparing the original slave's `dAuxiliaryQty` against the sum of `dAuxiliaryQty` on matching `sMinusSrcSlaveId` rows — if any imbalance, aborts with `sCcprkHaveRedData` ("已存在红冲数据，不允许重复提交"). Finally calls `Sp_afterSave_sPrj`.

**Invocation:** Bound to `gdsmodule.sSaveProName` on `2/4 新增采购退货` (`192116810113315221425660510`) — 采购管理 → 物料采购流程 (KPI流程操作菜单). Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. Pre-save peer is `Sp_beforeSave_sPrj`. xly-src ships `script/标版/30100101/Sp_Check_sPrj.sql` as the install body.
