## Narrative

**Business context:** 生产管理 / 排程 — per-plan-row machine-hour calculator (作者: 钱豹). Given one `mftproductionplanslave.sId`, derives the slave row's planned hours and machine-changeover (调机) hours using the machine's adjustable formula (`elemachine.sPlanCapacityId` / `sAdjustableFormulaId`), so the scheduler shows realistic time on each plan row.

**What it does:** Reads the slave's product/process/machine context from `mftproductionplanslave` joined to `EleMachine`. When an adjustable formula is configured, builds the formula's input tuple (`billSlave,billControl,billProcedure,billMaster,baseProduct` over `mftproductionplanslave,mftworkordercontrol,mftworkorderprocess,eleprocessparam,eleProduct,mftworkorderslave`) and calls `Sp_System_ReplaceField_Detail` to evaluate it, capturing the raw hour, an annotated `sAdjustHour` (formula trace), and a fallback message when the formula errors. Writes back to `mftproductionplanslave.dCalcHour1` and `sAdjustHour`. Returns the cumulative `p_dHour` to the caller.

**Invocation:** Called by procedure `Sp_Manufacture_InsertMftPlanSlave` (when a plan slave is inserted/refreshed) and `Sp_Manufacture_SetTime` (when plan times are re-derived). No direct Java caller and no form-master binding — strictly a helper inside the scheduling proc family.
