Material Validation

What is this?

Material validation ensures that all material master data:

  • Is complete
  • Is consistent across views
  • Meets SAP requirements
  • Can support procurement, inventory, and finance

Validation is the gate before materials become usable in SAP.

Why it exists?

Material master data drives:

  • Procurement
  • Inventory management
  • Financial valuation

If material data is wrong: → Inventory becomes unreliable
→ Financial statements become incorrect

Material master is the backbone of logistics and finance integration. :contentReference[oaicite:0]{index=0}

Types of Validation

1. Structural Validation

Checks mandatory fields exist

Examples:

  • Material type
  • Base unit of measure
  • Description

SAP enforces mandatory field checks depending on material type and configuration. :contentReference[oaicite:1]{index=1}

2. View-Level Validation

Checks required views are maintained

Examples:

  • Purchasing view → required for PO
  • Accounting view → required for valuation
  • MRP view → required for planning

Missing views = material unusable

3. Organizational Validation

Checks material is extended correctly

Levels:

  • Plant
  • Storage location
  • Company code (valuation)

Material must exist at correct org levels to be usable in processes. :contentReference[oaicite:2]{index=2}

4. Unit of Measure (UoM) Validation

Checks:

  • Base unit consistency
  • Conversion factors

Example:

  • 1 BOX = 10 EA

If wrong: → Inventory mismatch
→ Incorrect valuation

5. Valuation Validation (Critical)

Checks:

  • Valuation class
  • Price control (Standard / Moving Avg)
  • Price consistency

Material valuation directly affects financial accounting postings. :contentReference[oaicite:3]{index=3}

6. Data Consistency Validation

Checks relationships:

  • Material type ↔ allowed views
  • Plant ↔ procurement type
  • UoM ↔ pricing

Ensures logical correctness across fields.

7. Duplicate Validation

Checks:

  • Same item created multiple times

Criteria:

  • Description similarity
  • UoM
  • Usage

Duplicate materials cause: → Split inventory
→ Reporting errors

8. Process Readiness Validation

Checks if material can actually be used:

  • Can create PO?
  • Can post GR?
  • Can valuate stock?

If not: → Material is useless

Validation Mechanisms

Standard SAP Validation

  • Mandatory fields
  • Field selection rules
  • View requirements

Mass Validation

Tools:

  • MM17 (mass update/validation)
  • Reports (MM60, MMBE)

Used for: → Bulk migration checks :contentReference[oaicite:4]{index=4}

Custom Validation

  • Business rules
  • Data governance checks
  • Naming conventions

SAP requires standardized data formats for consistency and integration. :contentReference[oaicite:5]{index=5}

Validation Strategy (Migration)

Stage 1: Pre-Migration

  • Remove duplicates
  • Standardize units
  • Clean descriptions

Stage 2: During Migration

  • Validate mapping outputs
  • Check view completeness
  • Verify org extensions

Stage 3: Post-Migration

  • Run process tests (PO, GR, Invoice)
  • Validate stock and valuation
  • Reconcile inventory

Mapping Dependency

→ Material_Mapping

Validation ensures: → Mapping logic is correct

If validation fails: → Mapping is wrong

Process Impact

→ P2P_Procure_to_Pay

Failures lead to:

  • PO creation issues
  • GR posting failures
  • Incorrect inventory
  • Wrong financial postings

Common Issues

→ Material_Issues

Typical failures:

1. Missing Views

→ Material unusable

2. Wrong UoM

→ Inventory mismatch

3. Missing Valuation

→ FI posting failure

4. Incorrect Material Type

→ Process restrictions

5. Missing Plant Extension

→ Cannot transact

Anti-Pattern

❌ Validate after migration
❌ Ignore org-level data
❌ Assume Oracle data is clean

Correct:

→ Validate before, during, and after

Key Takeaway

Material validation is NOT:

→ Data checking

It is:

→ Ensuring the material behaves correctly across logistics and finance

If validation fails: → SAP is protecting your system from bad design
