Configuration

Quick answer

Like all customizing, MM config is built in DEV, transported through QAS to PRD, and never changed directly in production.

Key takeaways

  • A central part of MM config is automatic account determination (transaction OBYC), which decides the G/L accounts for goods…
  • Enterprise structure: plants, storage locations, purchasing organizations, and their assignments.
  • Material master settings: material types, number ranges, field selection.
  • Watch out: Account determination (OBYC) errors breaking goods movements.

What MM configuration covers

  • Enterprise structure: plants, storage locations, purchasing organizations, and their assignments.
  • Material master settings: material types, number ranges, field selection.
  • Purchasing: document types, release strategies, pricing schema.
  • Inventory & valuation: movement types, valuation, account determination.

Account determination (critical)

A central part of MM config is automatic account determination (transaction OBYC), which decides the G/L accounts for goods movements and invoice postings. Getting it right is what makes MM–FI integration work; getting it wrong causes "account determination" errors at goods receipt.

Configuration discipline

Like all customizing, MM config is built in DEV, transported through QAS to PRD, and never changed directly in production. Enterprise-structure decisions (plants, purchasing orgs) are foundational and hard to change, so plan them with the end-to-end process in mind.

Common pitfalls

  • Account determination (OBYC) errors breaking goods movements.
  • Poor enterprise-structure design.
  • Configuring directly in production.
