The error your ERP will never see
Character-Level MPN Mismatch
ERP validates field presence — not accuracy. One wrong character ('0' vs 'O', '1' vs 'I') clears every import check and reaches procurement undetected.
Row Part Number Manufacturer PN ERP Import BOM Transformer
R014 BR-0204 SKF-624-2RS1 ✓ PASS ✓ CLEAN
R031 BR-0204 SKF-62O-2RS1 ← zero entered as letter O ✓ PASS ⚠ FLAGGED
Without detection: Wrong bearing sourced. Line halted. Emergency expedite.  $12K–$50K in scrap, rework, and downtime. For one character.
Field scenario
400-part BOM. Release gate in 48 hours.
01
Engineer revises bearing spec BR-204 in one sub-assembly. The same part number appears in two others — different description, different procurement spec. ERP clears all three rows.
02
Procurement issues POs. Three incompatible variants ordered. Wrong parts arrive at assembly. No fit, no function.
03
Line down for 2 days. Wrong parts scrapped. Expedite fees. Launch date slips.
Cost of one BOM documentation error
$12,000 — $50,000
BOM Transformer flags the conflict at upload — before a single PO is issued.
Security & data handling
Zero-Retention Processing
Your BOM contains proprietary part numbers and supplier data. We never write it to disk, never share it, and never retain it after your session ends.
✓In-memory only — no file writes
✓Zero third-party data sharing
✓Session-scoped — nothing persists after audit
✓Your data never trains any model
✓Enterprise audit trail and DPA on request

What we catch
Critical

MPN Character Errors

'0' vs 'O', '8' vs 'B', '1' vs 'I' — the error class ERP import is architecturally blind to.

Critical

Cross-Assembly Duplicate Conflicts

Same part number across sub-assemblies with conflicting descriptions or specs. Leading cause of wrong-part orders.

Critical

Unit of Measure Conflicts

5MM vs 0.005M vs 5 for the same dimension. Catches the mismatch that breaks MRP calculations downstream.

Warning

Nomenclature Inconsistencies

"Bearing 6204" vs "BRG-6204" — same part, three identifiers. Causes split records and sourcing confusion.

Warning

Format & Encoding Violations

Mixed case, special characters, and whitespace that break ERP imports and automated ordering workflows.

Critical

Null & Missing Fields

Blank part numbers, empty descriptions, zero-quantity rows — every one a procurement failure waiting at the dock.
