## Narrative

**Business context:** 基础资料 / 工序 (Process base data) — when a process (`ELEPROCESS`) is renamed, renumbered, has its unit changed, or is moved to a different process classification in the **工序** maintenance page, this proc pushes the new `sProcessNo`/`sProcessName`/`sProcessUnit`/`sProcessClassifyId` (= `ELEPROCESS.sParentId`) to every historical production-report row that already references that process.

**What it does:** `SELECT sProcessNo, sProcessName, sProcessUnit, sParentId INTO @sProcessNo, @sProcessName, @sProcessUnit, @sProcessClassifyId FROM ELEPROCESS WHERE sId = sEleProcessId`, then `UPDATE ERPMERGEPRODUCTIONREPORT SET ... WHERE sProcessId = sEleProcessId`. One-shot denormalization push.

**Invocation:** Reached via `ProDao.proErpMergeBaseEleProcess(map)` → MyBatis `ProMapper.proErpMergeBaseEleProcess` (`CALL PRO_ERPMERGEBASEELEPROCESS(#{sEleProcessId})`). Fired by `ChangeEleProcessServiceImpl` (the JMS `CHANGE_GDS_MODULE` consumer for the process entity) after a base-data row mutates, keeping denormalized reporting tables in sync without a full rebuild.
