# `Sp_Check_sCut` (procedure) > 物料转换单据保存之前数据校验 - **Type:** PROCEDURE - **Deterministic:** NO - **SQL data access:** CONTAINS SQL ## Parameters | # | Mode | Name | Type | |---|---|---|---| | 1 | IN | `sTableName` | `varchar(100)` | | 2 | IN | `sGuid` | `varchar(100)` | | 3 | IN | `sFormGuid` | `varchar(100)` | | 4 | IN | `sLoginId` | `varchar(100)` | | 5 | IN | `sBrId` | `varchar(100)` | | 6 | IN | `sSuId` | `varchar(100)` | | 7 | IN | `iFlag` | `int` | | 8 | OUT | `sCode` | `int` | | 9 | OUT | `sReturn` | `varchar(4000)` | ## Body _Body is not pre-cached. To inspect: `mysql --defaults-file=~/.my.cnf -e 'SHOW CREATE PROCEDURE `Sp_Check_sCut`'`._ ## 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.
