## Narrative

**Business context:** Post-save validator nominally for 发外到货单据 (per procedure summary), targeting `opsoutsidearriveslave`. Reads `NetMoney`/`NetPrice` precision from `SysSystemSettings`, opens a cursor over `opsoutsidearriveslave` joined to `elematerials`/`sistax`, and recomputes per-row money/tax/qty fields against the material's 正算/反算 formula and tax rate — the same recompute pattern as `Sp_Check_sOis`/`Sp_Check_sOpc`/`Sp_Check_sOpn1`.

**What it does:** Inside the `top:` block, gates on `IFNULL(sFormGuid,'') <> ''`. For each slave row pulls `(sId, sMaterialsId, sMaterialsStyle, dMaterialsQty, dAuxiliaryQty, dMaterialsPrice, dMaterialsMoney, dRate, sSrcSlaveId, sMaterialsName, bInverse, sReComputeId, sComputeId, …)` and re-derives the money fields rounded to `p_NetMoney`/`p_NetPrice`.

**Invocation:** Status: appears orphaned. No `gdsmodule.sSaveProName`/`sSaveProNameBefore`/`sProcName`/`sDeleteProName` row references it; no form-master `sSqlStr` ref; no other DB routine calls it; xly-src grep finds only `script/标版/30100101/Sp_Check_sOpn.sql` (the install body). The 发外到货 flow appears to use `Sp_Check_sOpp` (整单发外) and `Sp_Check_sOpi` (整单发外入库) instead — candidate for maintainer audit.
