## Narrative

**Business context:** 设备管理 → 设备单据 — equipment-maintain-plan-change audit on `eptmachinemaintainchangemaster` (COMMENT `'设备保养时间变更'`). Approves a 设备保养时间变更 (reschedule request against an existing 设备保养计划), and on approval pushes the new date back into the original plan slave so the plan reflects the change.

**What it does:** Validates `sGuid`. With `iFlag=1`: guards on `bCheck=1`, `Update eptmachinemaintainchangemaster` to set `bCheck=1, sStatus=1, sCheckPerson, tCheckDate`, then `Update eptmachinemaintainplanslave` to overwrite `tPlanMaintainDate` with the change-bill's new date for the referenced plan slave. Uncheck reverses the master flags (does not undo the plan-slave date — flag for audit if reversibility matters).

**Invocation:** Status: appears orphaned. No live `gdsmodule.sProcName` binding, no `sSaveProName` hook, no other-routine CALLs, no xly-src reference (no install script, no Java) — candidate for maintainer audit. Likely either deprecated or bound only in customer-specific overrides for the 设备保养时间变更 form.
