## Narrative

**Business context:** 销售单据 / 商机机会 → 开发跟进 — toolbar-button handler that rolls a 商机机会产品 (sales-opportunity product line) back from "已开发" (developed) to the pre-development state, capturing a 退回原因 / 备注 in the process. Inverse of `Sp_saleschanceToSop_BtnEventTodevelop`.

**What it does:** Validates `sProInParam` (rejects with `paramsErro` via `Sp_Sis_GetConst` if too short). Parses `$.changeValue.sDevelopBackMemo` and the `$.params[*].value[*].sSlaveId` JSON array. For each slave id, `UPDATE salsaleschanceproduct SET tDevelopDate=NULL, sDevelopPerson='', bDevelop=0, sDevelopMemo='', sDevelopBackMemo=<memo> WHERE sId=<sSlaveId> AND sBrandsId=sBrId AND sSubsidiaryId=sSuId` — clearing the develop flag and timestamp, blanking the develop person and memo, and writing the user-supplied roll-back reason into `sDevelopBackMemo`.

**Invocation:** Dispatched dynamically by `GenericProcedureCallServiceImpl.doGenericProcedureCall()` (POST `/procedureCall/doGenericProcedureCall`) — the 退回开发 toolbar button on the 商机机会 / 开发跟进 grid names `Sp_saleschanceToSop_BtnEventDevelopBack` as the action. Companion procs: `Sp_saleschanceToSop_BtnEventTodevelop` (forward action, sets `bDevelop=1`), `Sp_saleschanceToSop_BtnEventDistribution` (assigns 业务类型).
