## Narrative

**Business context:** 成本核算 / 期间材料价格重算 — the "re-cost" counterpart to `Sp_System_MaterialsCost`. Same weighted-average algorithm (期初金额 + 采购入库 + 其它入库 / 同口径数量) but operating from the 月度成本 batch context: takes a JSON list of `sysaccountperiod` ids, undoes any prior 材料分摊 confirmation, and reruns the price computation. Lets accounting re-issue 材料价 for an already-priced period when adjustments arrive.

**What it does:** Validates `sProInParam` ≥ 13 chars and that the JSON `$.params[*].value[*].sId` list hits `sysaccountperiod`; for each id reads `sPeriodId`, refuses when `accordercostanalysis iType=1 bConfirm=1` or `accproductionmaterialsslave bConfirm=1` exists for the period, then follows the same temp-table / `Sp_MaterialsCarryforward` / `accmaterialsstore` / `mitmaterialsstoreadjustmoney*` rebuild flow as `Sp_System_MaterialsCost` to refresh prices.

**Invocation:** Status: appears orphaned at the procedure-call level (no proc-to-proc, gdsmodule, or form-master binding). Signature `(sProInParam JSON, sMakePerson, sBrId, sSuId, sReturn, sCode)` is the canonical `Sp_BtnEvent_*` dispatch shape — almost certainly invoked by `GenericProcedureCallServiceImpl.doGenericProcedureCall()` from a 重新计算材料价 button on the 月度成本 grid.
