From 78241f2b8d449e354348f0cf9e05f36927aa16ca Mon Sep 17 00:00:00 2001 From: Misaka_Company Date: Thu, 12 Feb 2026 15:54:50 +0800 Subject: [PATCH] fix: component worksheet rowCount false positive validation error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 ✅ Co-Authored-By: Claude Sonnet 4.5 --- .../Modules/M08_ComponentProcessor.bas | 44 ++-- VBA_BOMConverter/Modules/M09_BOMExtractor.bas | 28 ++- docs/BOM_Matching_Fix_Summary.md | 212 ++++++++++++++++++ 3 files changed, 252 insertions(+), 32 deletions(-) create mode 100644 docs/BOM_Matching_Fix_Summary.md diff --git a/VBA_BOMConverter/Modules/M08_ComponentProcessor.bas b/VBA_BOMConverter/Modules/M08_ComponentProcessor.bas index fdf8035..30b1a80 100644 --- a/VBA_BOMConverter/Modules/M08_ComponentProcessor.bas +++ b/VBA_BOMConverter/Modules/M08_ComponentProcessor.bas @@ -37,67 +37,61 @@ End Sub ' wsComponent -
