SAP Pricing & Condition Technique
The generic condition technique engine underlying pricing in SD, MM, and other modules.
The condition technique is one of those "once you get it, half of SAP suddenly makes sense" topics, and interviewers ask about it specifically because it's reused far beyond SD pricing - output determination, batch determination, account determination, and tax procedures all use the identical underlying mechanism, so demonstrating a real grasp of it signals broad configuration competence rather than memorized transaction paths.
The condition technique is like a customer-service escalation script that tries the most specific answer first (this exact customer and this exact product) and falls back to more generic answers (this product regardless of customer, or a company-wide default) only if nothing more specific is found, stopping the moment any match succeeds.
