General Exam Tips

💡Memory Aids
  • Sales Area = Sales Org + Dist Channel + Division (remember: S+D+D = Sad)
  • Shipping Point = Plant + Shipping Cond + Loading Grp (remember: P+S+L = PSL)
  • Document Flow: Always remember: Order → Delivery → Billing
  • ATP: Stock + In - Out
💡Question Keywords
  • “Always” or “Never” → These answers are often wrong
  • “Multiple” → Check if it’s N:1 or 1:N relationship
  • “Automatic” → Usually involves configuration/master data
  • “Manual” → Requires user intervention during processing
⚠️Read Carefully
  • Pay attention to: “Sales Organization” vs “Sales Area”
  • “Shipping Point” vs “Plant”
  • “Customer Master” vs “Customer Material Info Record”
  • “Condition Type” vs “Condition Record”
