## Narrative

**Business context:** 库存管理 → 成品库存 → 出库管理 → 成品领用单据 — post-save validator on `pitproductrejectmaster`/`pitproductrejectslave` (`sPtr` = product-takeout/reject). Despite the name, the proc backs the 成品领用 (and report-scrap) flow: ensures 红冲 records don't double-submit and that the out-store qty per row does not exceed either the source 计划 qty or the 质量事故 报废 qty.

**What it does:** Sets `sCode=1`, `iFlag=0`, clears `sReturn`. Reads `pitproductrejectmaster.sMinusSrcId`; if set, counts `pitproductrejectslave` rows whose original `dProductQty` plus summed reverse-charge `dProductQty` is non-zero — if any, aborts with `sCcprkHaveRedData` ("已存在红冲数据，不允许重复提交"). The commented 余数仓库 enforcement block is preserved. With a non-empty `sFormGuid`, opens a cursor over `pitproductrejectslave` and for each `sSrcSlaveId` checks two channels: (1) `mftproductionplanbillslave.dProcessQty - SUM(pitproductrejectslave.dProductQty)` and (2) `mftqualityaccidentmaster.dScarpQty - SUM(...)`. On negative result, concatenates either `sOdtInOrder` (same bill) or `sDataInScrapOrDispatch` (other bill numbers) with `sOutStockExceed` ("出库数量已超量"). Aborts with `sCode=-1` if `sReturn` is non-empty, otherwise calls `Sp_afterSave_sPtr`.

**Invocation:** Bound to `gdsmodule.sSaveProName` on `成品领用单据` (`101251240115015920999005840`) — 库存管理 → 成品库存 → 出库管理. Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. No `sSaveProNameBefore` peer on this module. xly-src ships `script/标版/30100101/Sp_Check_sPtr.sql` as the install body.
