# `Sp_Check_sDgn` (procedure) > 送货通知单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_sDgn`'`._ ## Narrative **Business context:** 销售管理 → 销售送货流程 → 送货通知单 (`saldelivernotifymaster/slave`) — post-save validator and money/qty back-calculator on the 送货通知单 form. Also serves 材料送货通知单单据 (`101251240115016140461755160`) which shares the same table. **What it does:** Initial guard: if any slave with `dProductQty>0 OR dGiveQty>0` has `bRemainderScrap=1`, aborts with `sCantChooseBfck` ("正数和备品数不为0时,不能勾选余数报废出库选项"). Reads `NetMoney/NetPrice` precision from `SysSystemSettings`. Cursors every just-saved `saldelivernotifyslave` row, joins `salsalesorderslave` (the originating sales-order line), and re-derives `dProductMoney/dProductPrice/dProductNoTaxMoney/dProductTaxMoney/dProductForeignMoney/dProductTaxForeignMoney/dNProductPrice/dProofingMoney/dPlateMoney/dKnifeMouldMoney` using the order's `dCurrencyRate` and `sistax.dRate` (forward/reverse calc by `bInverse`). **Invocation:** Bound to `gdsmodule.sSaveProName` on `送货通知单单据` (`15833158840002862255575040533000`) and `材料送货通知单单据` (`101251240115016140461755160`) — both under 销售管理 → 销售送货流程. Dispatched by `BusinessBaseServiceImpl.checkUpdate(..., "sSaveProName")` after the save batch commits. Pre-save peer is `Sp_beforeSave_sDgn`; audit handler is `Sp_Calc_sDgn`. xly-src ships `script/标版/30100101/Sp_Check_sDgn.sql` as the install body.
