## Narrative

**Business context:** Procedure variant of the material-qty unit converter — given a material guid + 规格 + 辅助数量, branches on `EleMaterials.sMaterialsUnit` vs `sAuxiliaryUnit` (令/张/吨/Ton/etc.) and the gram-weight + `CbxMaterialsUnit` (MM/CM/INCH) system setting to return either the converted quantity (`iType=0`) or the chosen auxiliary unit (`iType=1`). Same intent as the live `Fun_GetMaterialsQtyUnit` function but with the SELECT-returns-rowset shape instead of RETURN.

**What it does:** Reads `EleMaterials` columns into locals, computes 张/令/吨/Ton conversions from the printed-format 长×宽 + 克重 + `NetConversionRate` (INCH path) or simple multiplier-of-500 (令↔张), and SELECTs the result. Handles `bInverse` inversion and `bReel` (卷材) carve-out.

**Invocation:** Status: appears orphaned. No caller found in any channel (form-master, gdsmodule hooks, other routines, xly-src grep across all extensions). Superseded by the FUNCTION `Fun_GetMaterialsQtyUnit` (50+ proc callers + Java `CalculationStdServiceImpl`/`ReplaceFieldServiceImpl`) and its `Supple`/`BQ`/`_copy1` siblings — the function form fits MySQL's expression contexts the procedure cannot. Keep only as the pre-function reference implementation.
