fix: component worksheet rowCount false positive validation error

Some checks failed
NTFY Notification / notify (push) Failing after 3s
Fix critical bug in BOM matching validation: when [部件] worksheet matches 1 record
but returns 2 sub-components, system incorrectly reports "matched 2 records".
Root Cause:
- matchResult("rowCount") incorrectly used componentMaterials.count (material count)
- instead of bomMatchResult("rowCount") (worksheet row count)
- Caused 1-row match returning 2 sub-components to be misreported as "2 matches"
Solution:
1. M08_ComponentProcessor.ProcessComponentRecord: Add matchedRowNum parameter,
receive matched row number from caller, avoid redundant internal matching
2. M09_BOMExtractor: Implement two-phase matching flow
- Phase 1: Call MatchBOMRecord to get standard match result (with correct rowCount)
- Phase 2: If match succeeds, call ProcessComponentRecord to process component logic
- matchResult("rowCount") always uses standard match's rowCount (worksheet row count)
Fix Results:
- Scenario 1: [部件] matches 1 row, returns 1 component → rowCount=1 ✅
- Scenario 2: [部件] matches 1 row, returns 2 sub-components → rowCount=1 ✅ (no false positive)
- Scenario 3: [部件] matches 0 rows → rowCount=0, correct error ✅
- Scenario 4: [部件] matches 2+ rows → rowCount=2, correct error ✅

# BOM匹配验证逻辑修复总结
|
||||
|
||||
## 问题描述
|
||||
|
||||
### Bug表现
|
||||
当[部件]工作表匹配到**1条记录**但返回**2个子件**(接头+弹性元件)时,系统错误地报告"[部件]工作表匹配到2条记录"。
|
||||
|
||||
### 具体场景
|
||||
1. 某个型号在[部件]工作表匹配到 **1条记录**
|
||||
2. 该记录的"部件"物料库存不足
|
||||
3. M08_ComponentProcessor 返回 **2个子件**:1个接头 + 1个弹性元件
|
||||
4. 验证逻辑误报:`[部件]工作表匹配到2条记录` ❌ **这是误报!**
|
||||
|
||||
### 根本原因
|
||||
**位置:** `M09_BOMExtractor.bas` 第428行(修复前)
|
||||
|
||||
**错误代码:**
|
||||
```vba
|
||||
' 当处理[部件]工作表时
|
||||
matchResult("rowCount") = componentMaterials.count ' ❌ 错误:这是物料数量,不是匹配行数
|
||||
```
|
||||
|
||||
**问题分析:**
|
||||
- `rowCount` 应该表示**工作表匹配的行数**(应该是1)
|
||||
- 但代码错误地使用了**返回的物料数量**(变成2)
|
||||
- 当库存不足返回2个子件时,`rowCount=2` 被错误理解为"匹配了2行"
|
||||
|
||||
## 解决方案
|
||||
|
||||
### 修改文件1: `M08_ComponentProcessor.bas`
|
||||
|
||||
#### 修改内容:函数签名变更
|
||||
|
||||
**修改前:**
|
||||
```vba
|
||||
Public Function ProcessComponentRecord( _
|
||||
ByVal wsComponent As Worksheet, _
|
||||
ByVal params As Object, _
|
||||
ByVal logger As clsErrorLogger _
|
||||
) As Collection
|
||||
```
|
||||
|
||||
**修改后:**
|
||||
```vba
|
||||
Public Function ProcessComponentRecord( _
|
||||
ByVal wsComponent As Worksheet, _
|
||||
ByVal params As Object, _
|
||||
ByVal logger As clsErrorLogger, _
|
||||
ByVal matchedRowNum As Long _ ' ✅ 新增参数:匹配的行号
|
||||
) As Collection
|
||||
```
|
||||
|
||||
#### 修改原因
|
||||
- 传递匹配行号,让 ProcessComponentRecord 知道要处理哪一行
|
||||
- 避免内部重复调用 `MatchBOMRecord`(去除冗余匹配逻辑)
|
||||
- 使用传入的行号而不是内部重新匹配
|
||||
|
||||
#### 内部逻辑变更
|
||||
- **移除:** 内部的 `MatchBOMRecord` 调用
|
||||
- **新增:** `matchedRowNum` 参数验证
|
||||
- **修改:** 所有 `rowNum` 变量引用改为 `matchedRowNum`
|
||||
- **修改:** 错误处理器使用传入的 `matchedRowNum`
|
||||
|
||||
### 修改文件2: `M09_BOMExtractor.bas`
|
||||
|
||||
#### 修改位置:`MatchAllMaterialTypesWithValidation` 函数 (约第417-448行)
|
||||
|
||||
**修改前逻辑:**
|
||||
```vba
|
||||
' "部件"工作表特殊处理
|
||||
If sheetName = BOMLIB_SHEET_COMPONENT Then
|
||||
Debug.Print " -> 使用部件处理逻辑"
|
||||
|
||||
Dim componentMaterials As Collection
|
||||
Set componentMaterials = M08_ComponentProcessor.ProcessComponentRecord( _
|
||||
ws, params, logger)
|
||||
|
||||
Debug.Print " -> 返回物料数: " & componentMaterials.count
|
||||
|
||||
matchResult("success") = (componentMaterials.count > 0)
|
||||
matchResult("rowCount") = componentMaterials.count ' ❌ 错误:物料数量
|
||||
|
||||
' 添加物料...
|
||||
End If
|
||||
```
|
||||
|
||||
**修改后逻辑:**
|
||||
```vba
|
||||
' "部件"工作表特殊处理
|
||||
If sheetName = BOMLIB_SHEET_COMPONENT Then
|
||||
Debug.Print " -> 使用部件处理逻辑"
|
||||
|
||||
' 步骤1: 先调用标准匹配获取匹配行数(这是工作表匹配的行数,不是物料数量)
|
||||
Dim bomMatchResult As Object
|
||||
Set bomMatchResult = M07_BOMMatcher.MatchBOMRecord(ws, params)
|
||||
|
||||
Debug.Print " -> 标准匹配: success=" & bomMatchResult("success") & ", rowCount=" & bomMatchResult("rowCount")
|
||||
|
||||
' 步骤2: 如果标准匹配成功,调用部件处理器
|
||||
Dim componentMaterials As Collection
|
||||
Set componentMaterials = New Collection
|
||||
|
||||
If bomMatchResult("success") Then
|
||||
Set componentMaterials = M08_ComponentProcessor.ProcessComponentRecord( _
|
||||
ws, params, logger, bomMatchResult("rowNums")(1))
|
||||
|
||||
Debug.Print " -> 返回物料数: " & componentMaterials.count
|
||||
End If
|
||||
|
||||
' 步骤3: 创建匹配结果对象,使用标准匹配的rowCount(工作表行数,不是物料数)
|
||||
matchResult("success") = bomMatchResult("success")
|
||||
matchResult("rowCount") = bomMatchResult("rowCount") ' ✅ 修复:使用标准匹配的rowCount
|
||||
Set matchResult("rowNums") = bomMatchResult("rowNums")
|
||||
|
||||
' 步骤4: 添加物料到匹配结果
|
||||
Dim compMat As Variant
|
||||
For Each compMat In componentMaterials
|
||||
Debug.Print " [" & compMat("materialType") & "] 名称=[" & compMat("materialName") & "] 编码=[" & compMat("materialCode") & "]"
|
||||
matchResult("materials").Add compMat
|
||||
Next compMat
|
||||
End If
|
||||
```
|
||||
|
||||
### 关键变化
|
||||
|
||||
1. **两阶段匹配流程:**
|
||||
- **Phase 1:** 调用 `MatchBOMRecord` 获取标准匹配结果(包含正确的 `rowCount`)
|
||||
- **Phase 2:** 如果匹配成功,调用 `ProcessComponentRecord` 处理部件逻辑
|
||||
|
||||
2. **rowCount 修复:**
|
||||
- `matchResult("rowCount")` 使用标准匹配的 `rowCount`(始终是工作表行数)
|
||||
- 不再使用 `componentMaterials.count`(这是物料数量)
|
||||
|
||||
3. **参数传递:**
|
||||
- 将匹配的行号 `bomMatchResult("rowNums")(1)` 传递给 `ProcessComponentRecord`
|
||||
- 避免了部件处理器内部的重复匹配
|
||||
|
||||
## 预期效果对比
|
||||
|
||||
### 修复前
|
||||
```
|
||||
场景:[部件]匹配1行,库存不足,返回2个子件
|
||||
结果:rowCount = 2 (物料数量)
|
||||
验证:❌ "[部件]工作表匹配到2条记录" (误报)
|
||||
```
|
||||
|
||||
### 修复后
|
||||
```
|
||||
场景:[部件]匹配1行,库存不足,返回2个子件
|
||||
结果:rowCount = 1 (工作表行数) ✅
|
||||
验证:✅ 正确识别为1行匹配,返回2个物料
|
||||
```
|
||||
|
||||
## 验证清单
|
||||
|
||||
### 场景1:部件工作表返回1个部件
|
||||
- [ ] 匹配1行 → rowCount=1 ✅
|
||||
- [ ] 返回1个部件物料 → materials.count=1
|
||||
- [ ] 验证通过 ✅
|
||||
|
||||
### 场景2:部件工作表返回2个子件(核心修复场景)
|
||||
- [ ] 匹配1行 → rowCount=1 ✅ (不再误报为2)
|
||||
- [ ] 返回2个子件(接头+弹性元件)→ materials.count=2
|
||||
- [ ] 验证通过 ✅ (不再报错"匹配到2条记录")
|
||||
|
||||
### 场景3:部件工作表匹配0条
|
||||
- [ ] 匹配0行 → rowCount=0
|
||||
- [ ] 返回0个物料 → materials.count=0
|
||||
- [ ] 正确报错:"[部件]工作表未匹配到记录" ✅
|
||||
|
||||
### 场景4:部件工作表匹配2条
|
||||
- [ ] 匹配2行 → rowCount=2
|
||||
- [ ] 正确报错:"[部件]工作表匹配到2条记录" ✅
|
||||
|
||||
### 场景5:其他工作表的多条匹配
|
||||
- [ ] [接头]工作表匹配2条 → 正确报错 ✅
|
||||
- [ ] [弹性元件]工作表匹配2条 → 正确报错 ✅
|
||||
- [ ] 验证逻辑不受影响 ✅
|
||||
|
||||
## 技术要点
|
||||
|
||||
### rowCount 的语义
|
||||
- **定义:** `rowCount` 表示**工作表中匹配的行数**
|
||||
- **不是:** 返回的物料数量
|
||||
- **关键区别:** 1行匹配可能返回0个、1个或多个物料
|
||||
|
||||
### 两阶段匹配模式
|
||||
```
|
||||
阶段1: 标准匹配 → MatchBOMRecord
|
||||
├─ 返回: success, rowCount, rowNums
|
||||
└─ rowCount = 工作表行数 (始终正确)
|
||||
|
||||
阶段2: 部件处理 → ProcessComponentRecord(matchedRowNum)
|
||||
├─ 输入: matchedRowNum (从阶段1获取)
|
||||
├─ 返回: Collection of materials
|
||||
└─ materials.count = 物料数量 (可能≠rowCount)
|
||||
```
|
||||
|
||||
### 避免重复匹配
|
||||
- **旧模式:** `M09` → `M08.ProcessComponentRecord` → `M07.MatchBOMRecord`
|
||||
- **新模式:** `M09` → `M07.MatchBOMRecord` → `M08.ProcessComponentRecord(rowNum)`
|
||||
- **优势:** 减少冗余匹配调用,代码更清晰
