## Narrative

**Business context:** 材料库存 → 材料库单据 → 材料库存调整单据 — material-stock adjustment audit / un-audit on `MitMaterialsStoreAdjustmentMaster`. The 库存调整 is the manual escape hatch for fixing on-hand totals that no other transaction can correct (lost/found stock, post-stocktake patches). Auditing the doc commits the adjustment into `MitMaterialsStore` and refreshes the `EleMaterialsStock` snapshot.

**What it does:** Defaults the IN params, branches on `iFlag`. On `iFlag=1` flips `MitMaterialsStoreAdjustmentMaster.bCheck=1` and `INSERT INTO EleMaterialsStock` re-aggregating from `MitMaterialsStore` after the adjustment rows post. On `iFlag=0` runs `Delete From MitMaterialsStore` for the doc's adjustment rows and `UPDATE EleMaterialsStock` to restore prior on-hand.

**Invocation:** Bound to `gdsmodule.sProcName` on `材料库存调整单据` (sId `192116810113315227379171200`) under 材料库存 → 材料库单据.
