## Narrative

**Business context:** 销售管理 → 销售送货流程 → 销售对账&开票 — post-save validator on `salsalescheckingmaster`/`salsalescheckingslave`/`salsalescheckingchild`. Ensures the reconciliation qty (`dProductQty`+`dGiveQty`) on each line does not exceed the corresponding 送货单 (delivery note) qty, then recomputes the per-line money columns from the foreign-currency total at the configured precision.

**What it does:** Sets `sCode=1`, `iFlag=0`, clears `sReturn`. Reads `NetMoney`/`NetPrice` precisions. When `sFormGuid` is set, opens a cursor over `salsalescheckingslave` rows for `sParentId=sGuid`. For each row with a non-empty `sSrcSlaveId`: aggregates summed `dProductQty+dGiveQty` per `sSrcSlaveId` and joins to `SalDeliverGoodsSlave` — if the summed reconciliation qty exceeds the delivery qty (`Q.dProductQty + Q.dGiveQty`), aborts with concatenated `对账数量已超过送货单数量；` plus the offending bill number. A symmetric overrun guard runs again against the quotation/order qty (the same group concat / count idiom). Then recomputes `dProductMoney = ROUND(dProductForeignMoney * dCurrencyRate, p_NetMoney)`, `dProductNoTaxMoney = ROUND(dProductMoney / (1 + dRate/100), p_NetMoney)`, `dProductTaxMoney = dProductMoney - dProductNoTaxMoney` per row and writes them back via a dynamic `UPDATE salsalescheckingslave`. Finally calls `Sp_afterSave_sSck`.

**Invocation:** Bound to `gdsmodule.sSaveProName` on `销售对账单据` (`11811781131121915184849572550`) — 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_sSck`. xly-src ships `script/标版/30100101/Sp_Check_sSck.sql` as the install body.
