## Narrative

**Business context:** KPI流程操作菜单 → 物料采购流程 → 2/4 新增采购退货 — purchase-rejection (采购退货, return-to-supplier) audit on `PurPurchaseRejectMaster`/`Slave`. The check posts the return out of material stock, registers the negative payable, and back-stamps the matched stock-in line; the uncheck rolls every leg back.

**What it does:** Guards on `bInvalid`/`SysLocking` via a join on `PurPurchaseRejectSlave`. Aggregates `dMaterialsMoney`/`dMaterialsTaxMoney` from the slave; reads supplier from the master. On `iFlag=1`: enforces `Sp_calc_materialsstoreLimit` to refuse uncheck-blocking shortages; calls `Sp_System_AutoMaterialsPriceSingle` to refresh material last-price post-return; deletes any stale `MitMaterialsStore`/`CahPaymentables` for this bill and reinserts the negated movement rows + payable row (`INSERT INTO MitMaterialsStore`, `INSERT INTO EleMaterialsStock`); updates `EleMaterialsStock` aggregate; back-stamps `dRejectQty` into `purpurchaseinstoreslave`/`purpurchaseorderslave`; flips `bCheck=1, sStatus=1` on `PurPurchaseRejectMaster`. `iFlag=0` calls `Sp_Bill_Used` to refuse uncheck when downstream rows depend on it, then reverses.

**Invocation:** Bound to `gdsmodule.sProcName` on 2/4 新增采购退货 (sId `192116810113315221425660510`, parent 物料采购流程) — dispatched by `BusinessBaseServiceImpl.getPrcName(sFormGuid, …)` on the audit/un-audit button. xly-src ships `script/标版/30100101/Sp_Calc_sPrj.sql` (install) and `Sp_Check_sPrj.sql` (cross-check helper invoked before audit).
