## Narrative

**Business context:** 2/4 新增销售退货 → 销售送货流程 → KPI流程操作菜单 — header says 退货单保存后反写数量. Thin save-phase 反写 wrapper in the `Sp_afterSave_s<Code>` family that delegates the actual qty back-write to `Sp_saveReturn_sRgd`.

**What it does:** Declares unused locals `p_sMasterSql`/`sDeliverSrc`, wraps `sGuid` in double-quotes if not already quoted, then unconditionally calls `Sp_saveReturn_sRgd(sGuid, sBrId, sSuId, 2, @sCode, @sReturn)` (iFlag=2 = "after save" phase). Does not propagate the inner `@sCode`/`@sReturn` back to its own OUT params.

**Invocation:** Called by `Sp_Check_sRgd` (the save-commit dispatch proc bound via `gdsmodule.sSaveProName` on 2/4 新增销售退货 `11811781131121915179924871530`, with `sSaveProNameBefore='Sp_beforeSave_sRgd'`) near the tail of a successful save. `Sp_Invalid_backwriting` has no dispatch entry for this form.
