## Narrative

**Business context:** 采购发票 → 物料采购流程 → KPI流程操作菜单 — header says 采购发票保存后反写报价数量. Thin save-phase wrapper in the `Sp_afterSave_s<Code>` family that delegates the qty back-write to `Sp_saveReturn_sPiv`.

**What it does:** Wraps `sGuid` in double-quotes if not already quoted and, when `sGuid` is non-empty, calls `Sp_saveReturn_sPiv(sGuid, sBrId, sSuId, 2, @sCode, @sReturn)`. Does not propagate the inner `@sCode`/`@sReturn` to its own OUT params. A `-- set sCode = 1;` debug comment sits below the inner BEGIN.

**Invocation:** Reached only through `Sp_Check_sPiv`, which is bound via `gdsmodule.sSaveProName` on 采购发票. Not present in the `Sp_Invalid_backwriting` form-id dispatch table — invalidate/un-invalidate of 采购发票 does not currently re-trigger the qty back-write.
