# `Sp_Check_sOpkg` (procedure) > 发外发票单据保存之前数据校验 - **Type:** PROCEDURE - **Deterministic:** NO - **SQL data access:** CONTAINS SQL ## Parameters | # | Mode | Name | Type | |---|---|---|---| | 1 | IN | `sTableName` | `varchar(100)` | | 2 | IN | `sGuid` | `varchar(100)` | | 3 | IN | `sFormGuid` | `varchar(100)` | | 4 | IN | `sLoginId` | `varchar(100)` | | 5 | IN | `sBrId` | `varchar(100)` | | 6 | IN | `sSuId` | `varchar(100)` | | 7 | IN | `iFlag` | `int` | | 8 | OUT | `sCode` | `int` | | 9 | OUT | `sReturn` | `varchar(4000)` | ## Body _Body is not pre-cached. To inspect: `mysql --defaults-file=~/.my.cnf -e 'SHOW CREATE PROCEDURE `Sp_Check_sOpkg`'`._ ## Narrative **Business context:** KPI流程操作菜单 → 发外加工流程 → 发外对账 — post-save validator on `opsoutsidecheckingmaster`. Prevents mixed 烟包/非烟包 reconciliation, blocks duplicate-source 发外确认 selections, then spreads the master-level 折扣 (discount) money across slaves proportionally and re-applies the price/tax recompute used elsewhere in the 发外 family. **What it does:** Reads `NetMoney`/`NetPrice` precision from `SysSystemSettings`. Aborts if `opsoutsidecheckingslave` joined to `elecustomer`/`siscustomerproperty` mixes 烟包 with non-烟包 customers (`sYbNybCantReconciled`), and aborts if any non-红冲 slave references the same `(sSrcNo, sSrcSlaveId)` twice (`sFwqrDataDuplicate`). Then seeds `dMaterialsOldPrice` from `dMaterialsPrice`, computes the slave total, and apportions the master `dLossAllMoney` across slaves as `sLossType='折扣'` per `(qty × oldPrice / total)`. Finishes with the standard cursor-driven money/tax recompute over `opsoutsidecheckingslave` joined to `elematerials`/`sistax`. **Invocation:** Bound to `gdsmodule.sSaveProName` (post-save) on `发外对账` (`192116810113315235850403280`, under KPI流程操作菜单 → 发外加工流程). Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. xly-src ships `script/标版/30100101/Sp_Check_sOpkg.sql` as the install body. The procedure summary text (`发外发票单据保存之前数据校验`) misnames the form — actual binding is 发外对账, not 发外发票.
