# `Sp_afterSave_sWXKK` (procedure) > 外协商扣款反写 - **Type:** PROCEDURE - **Deterministic:** NO - **SQL data access:** CONTAINS SQL ## Parameters | # | Mode | Name | Type | |---|---|---|---| | 1 | IN | `sGuid` | `varchar(2000)` | | 2 | IN | `sBrId` | `varchar(100)` | | 3 | IN | `sSuId` | `varchar(100)` | | 4 | OUT | `sCode` | `int` | | 5 | OUT | `sReturn` | `varchar(4000)` | ## Body _Body is not pre-cached. To inspect: `mysql --defaults-file=~/.my.cnf -e 'SHOW CREATE PROCEDURE `Sp_afterSave_sWXKK`'`._ ## Narrative **Business context:** 外协入库扣款单据 (operates on `opsoutsideinstorededmaster`/`opsoutsideinstorededslave`) — header says 外协商扣款反写. Carries real save-phase logic: validates that every deduction line has a negative `dMaterialsPrice`, then rolls up the master `dOKMaterialsMoney` total before delegating downstream qty back-write to `Sp_saveReturn_sWXKK`. **What it does:** When `sGuid` is non-empty: (1) counts slave rows where `dMaterialsPrice > 0`; if any exist, sets `sCode = -1`, fetches the localized error via `Fun_Sis_GetConstNew('sGykkNagativeNum', ...)`, and `LEAVE top`. (2) Updates the master's `dOKMaterialsMoney = 0 - SUM(dMaterialsMoney)` over the slaves. (3) Calls `Sp_saveReturn_sWXKK(sGuid, sBrId, sSuId, 2, @sCode, @sReturn)`. The further `mftqualityaccidentmaster.dBackDeductionSupplyMoney` denorm UPDATE chain is fully commented out. **Invocation:** Status: appears dormant. No `gdsmodule.sSaveProName`/`sDeleteProName` slot in this database points at this proc, no `Sp_Check_sWXKK` exists, `Sp_Invalid_backwriting` has no dispatch entry for any 外协扣款 form, and no other routine references it. Candidate for maintainer audit.
