## Narrative

**Business context:** 销售管理 → 销售送货流程 → 新增销售退货 — post-save validator on `salrejectgoodsmaster`/`salrejectgoodsslave` (`sRgd` = sales-reject-goods despite the comment calling out 材料销售退货). Two business rules: deny duplicate 红冲 submissions for the same source bill, and forbid mixing different `sSlaveType` (退货类型) within one return note. Also bridges to `Sp_Check_dOraQtyTs` for over-quantity guard.

**What it does:** Sets `sCode=1`, `iFlag=0`, clears `sReturn`. Reads `pitproductrejectmaster.sMinusSrcId` (red-charge source). If set, joins original slave rows with summed reverse-charge `dProductQty` per `sMinusSrcSlaveId` (only against non-invalid masters) and aborts with `sCcprkHaveRedData` ("已存在红冲数据，不允许重复提交") when any imbalance survives. Then `SELECT COUNT(DISTINCT sSlaveType) FROM salrejectgoodsslave WHERE sParentId=sGuid` — if >1, aborts with `sReturnOrderCantDiffrentType` ("不同退货类型的退货申请单不能做在同一个退货单上"). Opens a cursor over `viw_salrejectgoods` (the large block of further per-slave 余数库 reconciliation and auto-inserting split rows is fully commented out). Calls `Sp_Check_dOraQtyTs('salrejectgoodsslave', 'dProductQty', ...)` for the family-shared over-qty check, then `Sp_afterSave_sRgd`.

**Invocation:** Bound to `gdsmodule.sSaveProName` on `2/4 新增销售退货` (`11811781131121915179924871530`) — 销售管理 → 销售送货流程 (KPI流程操作菜单). Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. Pre-save peer is `Sp_beforeSave_sRgd`. xly-src ships `script/标版/30100101/Sp_Check_sRgd.sql` as the install body.
