To inspect: `mysql --defaults-file=~/.my.cnf -e 'SHOW CREATE PROCEDURE `Sp_Check_sMpa`'`._ ## Narrative **Business context:** 生产执行 → MES单据 → 领料申请单据 / 补料申请单据 / 补版申请单据 — post-save validator on `mitproductionapplymaster`. Same proc serves all three申请 variants (领料/补料/补版) because they share the same master/slave tables. **What it does:** Reads `NetMoney`/`NetPrice` precision from `SysSystemSettings`, then runs three gating checks: (1) every requested material must have `sWorkCenterId` matching `elematerialsworkcenter` for the requesting department, else aborts with `sMaterialNeedWorkCenter`; (2) materials currently mid-工艺变更 (open `mftprocesschangemaster` of sType=1 with changed `sMaterialsId`/`sMaterialsStyle`) are blocked with `sMaterialInChange`; (3) once both pass, dedupes slave rows by `(sMaterialsId, sMaterialsStyle, sParentId)` and branches on `sFormGuid` to apply form-specific rules per the embedded comment block. **Invocation:** Bound to `gdsmodule.sSaveProName` (post-save) on `补料申请单据` (`12012615914116395420093200`), `补版申请单据` (`12012615914116395420566910`) and `领料申请单据` (`101251240115016056026128440`), all under 生产执行 → MES单据.
