Frequently asked questions about material codification, cleansing, UNSPSC and the VCode approach.

Material Codification

Why does codification matter for MRO materials?+

Without consistent codification, the same bearing might be recorded under dozens of different descriptions. This causes duplicate purchasing, excess stock, missed reorder points and ERP data quality issues.

What is UNSPSC-based material codification?+

UNSPSC (United Nations Standard Products and Services Code) is an internationally used classification system for products and services. It organizes items into four hierarchical levels: Segment, Family, Class and Commodity. UNSPSC-based codification helps organizations classify materials consistently and supports procurement analysis, spend reporting and supplier categorization.

What is an internal material code?+

An internal material code is a structured identifier unique to your organisation — typically following a Group-Subgroup-Noun-Modifier-Attribute-Serial format — used to identify items in your ERP.

How does AI help in material codification?+

AI can interpret unstructured material descriptions, correct spelling, understand abbreviations, extract technical specifications and suggest standardized descriptions. It can also recommend UNSPSC classifications and identify potential duplicates. Expert validation is important for ambiguous materials and specifications that could affect the correct classification.

How does VCode structure a material description?+

VCode uses a noun-modifier-attribute format. For example: 'VALVE, GATE, DN50, PN16, BODY:CS, END:FLANGE, STANDARD:API600' — each attribute is defined for the specific material class.

Can AI identify duplicate materials?+

Yes. AI can compare material descriptions, dimensions, grades, manufacturer part numbers and other technical attributes to identify exact or potential duplicates. Similarity matching helps uncover records created under different descriptions. Suspected duplicates should be verified before records are merged or deactivated.

What material classes does VCode cover?+

VCode covers a wide range of MRO classes including valves, pumps, motors, bearings, seals, fasteners, pipes, fittings, filters, instruments, cables, switchgear, and more.

What is the difference between a material code and a UNSPSC code?+

A material code is an organization's internal identifier for a specific material master record. A UNSPSC code classifies the type of product or service. An organization can retain its existing SAP or ERP material code while maintaining the appropriate UNSPSC classification as a separate field.

How are standardized material descriptions created?+

Standardized descriptions follow consistent naming conventions based on the material category. A typical structure identifies the primary noun, relevant modifiers and technical attributes such as size, grade, rating or model. Category-specific rules help preserve critical specifications and make materials easier to search, compare and identify.

Can existing SAP or ERP material masters be codified?+

Yes. Existing material master data can be exported from SAP, ERPNext or other ERP systems for analysis and codification. The process can standardize descriptions, identify potential duplicates, map materials to UNSPSC and flag missing information. Approved results can then be prepared for upload using the client's ERP procedures.

Does UNSPSC replace our existing material coding system?+

No. UNSPSC is a product and service classification system, not a mandatory replacement for an organization's internal material codes. Existing codes can be retained while UNSPSC classifications are added separately. This approach supports standardized classification without unnecessarily changing established ERP references or disrupting business operations.

What information is required to codify a material?+

Useful input includes the existing material description, manufacturer or part number, dimensions, material grade, technical specifications and unit of measurement. Not every field is required for every material. Where important information is missing, the codification process should flag the record for clarification rather than inventing specifications.

Can AI codify materials from unstructured descriptions?+

Yes. AI can process descriptions containing abbreviations, spelling errors, inconsistent word order and common industry terminology. It can extract meaningful details and propose standardized descriptions and UNSPSC classifications. Results should be checked against available technical data, particularly when incomplete descriptions could lead to incorrect identification.

What is the difference between a noun, modifier and attribute?+

The noun identifies what the material is, the modifier describes its type or form, and attributes capture its distinguishing technical characteristics. For example, in a ball bearing, 'bearing' is the noun, 'ball' is a modifier, and details such as bore size, series and shielding arrangement are attributes. The exact rules should be consistent across the material master.

Can the same material have different descriptions in different departments?+

Yes. Departments, plants and suppliers often describe the same material differently because of local terminology, abbreviations or naming practices. Material codification standardizes these descriptions and identifies potential duplicates while preserving original descriptions and source references for traceability and verification.

How does material codification help reduce inventory duplication?+

Standardized descriptions and duplicate-detection techniques help identify materials that may already exist under different codes or descriptions. After technical verification, confirmed duplicates can be considered for consolidation under the organization's approved procedures. This can improve inventory visibility, reduce unnecessary material creation and support better purchasing decisions.

Can UNSPSC be used for spare parts and maintenance materials?+

Yes. UNSPSC covers many products and services used in industrial procurement, including equipment, components and maintenance supplies. The appropriate code depends on the actual product and its classification in the applicable UNSPSC version. Specialized spare parts may require additional technical information to identify the most suitable commodity code.

Does every material require the same set of attributes?+

No. Required attributes depend on the material category. A bearing may require bore size and bearing type, a cable may require conductor size and voltage rating, and a valve may require pressure rating, end connection and body material. Category-specific validation rules help ensure that essential specifications are captured consistently.

How are uncertain UNSPSC classifications handled?+

When multiple UNSPSC classifications appear plausible, the system can present candidate codes with their official descriptions and supporting rationale. Records with insufficient information or uncertain matches should be flagged for expert review. This approach helps prevent unverified AI suggestions from becoming accepted material master data.

Can material codification be integrated with SAP, ERPNext or other ERP systems?+

Yes. Approved codification results can be prepared in a format compatible with the target ERP's data structure and import procedures. Integration may involve spreadsheets, APIs or other approved interfaces, depending on the system. Mandatory fields, validation rules, testing and authorization should be addressed before updating production material masters.

Will material codification change our existing material codes?+

Not necessarily. Existing material codes can be retained while descriptions are standardized and UNSPSC classifications are added. If duplicate records or obsolete codes are identified, any consolidation or renumbering should follow the client's approval process and preserve historical references, transaction traceability and ERP integrity.

Can material codification identify missing technical specifications?+

Yes. Category-specific rules can flag missing or inconsistent details such as dimensions, grades, pressure ratings, voltage, connection types or manufacturer part numbers. These checks help prioritize records requiring clarification and improve the completeness of material master data before final approval.
