## Narrative

**Business context:** 物料管理 → 物料转换单据 (`mitmaterialscutmaster/slave`) — post-save red-stroke (红冲) guard. Blocks a duplicate red-stroke save: if the document is a red-stroke (`sMinusSrcId` set) and the upstream source's slaves no longer net to zero after this attempt, the save is refused.

**What it does:** Reads `sMinusSrcId` from `mitmaterialscutmaster` for `sId=sGuid`. If non-empty, joins the original document's `mitmaterialscutslave` against the sum of all already-issued red-stroke slaves (`SUM(dAuxiliaryQty) GROUP BY sMinusSrcSlaveId`); if any source line's `dAuxiliaryQty + counter-qty <> 0`, aborts with `sCode=-1` and the localised `sCcprkHaveRedData` ("已存在红冲数据，不允许重复提交") message from `Fun_Sis_GetConstNew`. No work on non-red-stroke documents.

**Invocation:** Bound to `gdsmodule.sSaveProName` on `物料转换单据` (`101251168116315839165634020`) under 物料管理 → 仓储管理. Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. xly-src ships `script/标版/30100101/Sp_Check_sCut.sql` as the install body.
