Top SAP Interview Questions and Answers (All Modules Covered)
Here’s a curated set of the most frequently asked SAP interview questions, spanning General SAP concepts, FICO, SD, MM, ABAP, HCM, Basis, and S/4HANA — ideal for quick revision before your interview.
General SAP & S/4HANA
1. What is SAP and why is it widely used?
SAP is an ERP (Enterprise Resource Planning) software that integrates core business processes — finance, sales, procurement, production, and HR — into one unified platform. It improves data accuracy, eliminates departmental silos, and enables real-time decision-making.
2. What is the difference between SAP ECC and SAP S/4HANA?
SAP ECC runs on traditional relational databases with batch-heavy processing and complex data structures. S/4HANA runs on the in-memory HANA database, offering real-time analytics, a simplified data model, and a Fiori-based user interface instead of classic SAP GUI transactions.
3. What is SAP Fiori?
Fiori is SAP’s modern, role-based user interface used across S/4HANA. It offers responsive, mobile-friendly apps for tasks like managing sales orders, approvals, and dashboards, replacing many traditional GUI transaction screens.
4. Explain SAP’s three-tier architecture?
It consists of the Presentation layer (user interface), Application layer (business logic and processing), and Database layer (data storage). This separation allows scalability and centralized data management.
5. What are the different types of SAP modules?
SAP modules are broadly divided into Functional modules (FICO, SD, MM, HCM, PP) which handle business processes, and Technical modules (ABAP, Basis, NetWeaver) which handle development, customization, and system administration.
SAP FICO
6. What is a Company Code in SAP FI?
A Company Code is the smallest organizational unit in Financial Accounting for which a complete set of financial statements — balance sheet and profit & loss — can be generated.
7. What is a Fiscal Year Variant?
It defines the start and end dates of a company’s accounting year, along with posting periods and special periods for year-end adjustments, ensuring accurate and legally compliant financial reporting.
8. What is Credit Control in SAP FI?
Credit Control is a risk management practice where the system automatically checks a customer’s credit limit against their outstanding orders, deliveries, and invoices before allowing further transactions.
9. What is the difference between Company Code and Controlling Area?
Company Code is a Financial Accounting unit used for external reporting, while Controlling Area is used for internal cost tracking and management reporting, and can span across multiple company codes.
SAP SD (Sales and Distribution)
10. What is the Order-to-Cash (O2C) cycle?
O2C is the end-to-end sales process starting from customer inquiry and sales order creation, through delivery and billing, and ending with payment collection — integrating SD with FI for revenue and receivables posting.
11. What is a Distribution Channel in SAP SD?
It defines how a company sells and delivers products — such as direct sales, wholesale, retail, or online — and controls pricing, discounts, and customer-specific sales conditions for that channel.
12. What are Partner Functions in SAP SD?
Partner Functions define the roles different business partners play in a sales transaction — such as who places the order (sold-to), who receives goods (ship-to), who is billed, and who pays.
13. How would you troubleshoot a pricing issue in a sales order?
Start by checking pricing procedure determination — verify the Sales Area, Customer Pricing Procedure in the customer master, and Document Pricing Procedure on the sales document type, since a mismatch here typically prevents pricing from triggering correctly.
SAP MM (Materials Management)
14. What is the Procure-to-Pay (P2P) cycle?
P2P covers the entire procurement process — from purchase requisition and purchase order creation, through goods receipt and invoice verification, to final vendor payment.
15. How is pricing calculated in a Purchase Order?
Pricing is built using a Pricing Procedure made up of Condition Types, Access Sequences, and Condition Tables. The system pulls prices from Purchasing Info Records, Contracts, or Scheduling Agreements to arrive at the final net price.
16. How would you reverse an incorrect Goods Receipt?
First identify the movement type and material document from the original GR posting, then reverse it using the corresponding reversal movement type (e.g., 102 for a 101 GR), ensuring inventory and FI postings are corrected accordingly.
SAP ABAP
17. What is an Internal Table in ABAP, and why does its type matter for performance?
An internal table is a temporary, in-memory data structure used to process data during program execution. Choosing the right type — standard, sorted, or hashed — significantly affects performance, especially for large data reads using binary search or key-based access.
18. What is SAP Script used for?
SAP Script is a tool for designing and managing formatted business documents like invoices, purchase orders, and delivery notes, allowing custom layouts tied to business transactions.
SAP HCM & Basis
19. What is the difference between Personnel Administration and Organizational Management in SAP HCM?
Personnel Administration manages individual employee master data (personal details, contracts, payroll info), while Organizational Management handles the structural side — org units, positions, and reporting hierarchies.
20. What is a Transport Request in SAP Basis?
A Transport Request is used to move configuration or development changes from one SAP system to another (e.g., Development to Quality to Production) in a controlled, auditable way, ensuring changes are tested before reaching the live system.
21. What is Master Data in SAP?
Master Data is permanent business data used across multiple transactions. Examples include Customer Master, Vendor Master, Material Master, G/L Accounts, and Employee Master. It is created once and reused throughout the system.
22. What is Transaction Data?
Transaction Data is generated during day-to-day business operations. Examples include Sales Orders, Purchase Orders, Goods Receipts, Invoices, and Journal Entries.
23. What is a Client in SAP?
A Client is the highest organizational unit in SAP. It contains its own master data, users, and configuration. Multiple clients can exist within one SAP system for development, testing, and production.
24. What is SAP HANA, and why is it faster?
SAP HANA is an in-memory database that stores data in RAM rather than on disk. This enables extremely fast data processing, real-time reporting, advanced analytics, and simplified database structures.
25. What is the difference between OLTP and OLAP?
OLTP (Online Transaction Processing): Handles day-to-day business transactions like order creation and invoice posting.
OLAP (Online Analytical Processing): Used for reporting, analysis, dashboards, and business intelligence.
26. What is a Business Partner in SAP S/4HANA?
Business Partner is the central master data object in SAP S/4HANA that manages customers, vendors, and other business entities in one unified structure, replacing separate customer and vendor master records.
27. What is a Material Master?
The Material Master contains all information about a material required for purchasing, inventory management, sales, production, and accounting. It is one of the most important master data objects in SAP.
28. What are Movement Types in SAP MM?
Movement Types define the type of inventory transaction being performed.
Examples:
101 – Goods Receipt
102 – Reversal of Goods Receipt
201 – Goods Issue to Cost Center
261 – Goods Issue for Production
551 – Inventory Scrapping
29. What is an Accounting Document?
An Accounting Document records every financial transaction in SAP FI. It contains document header information and line items that impact G/L accounts, customers, or vendors.
30. Explain the concept of Posting Periods.
Posting Periods control when financial transactions can be posted. Once a period is closed, users cannot post entries unless the period is reopened by an authorized user.
31. What is a Sales Area in SAP SD?
A Sales Area is a combination of:
Sales Organization
Distribution Channel
Division
It determines how sales transactions are processed for customers.
32. What is a Purchase Requisition?

33. What is the difference between Purchase Requisition and Purchase Order?
Purchase Requisition
Purchase Order
Internal request
External document sent to vendor
No legal commitment
Legally binding document
Created by requester

BAPI (Business Application Programming Interface) is a standardized SAP programming interface that allows external applications to interact securely with SAP business objects.
37. What is RFC in SAP?
RFC (Remote Function Call) enables communication between SAP systems or between SAP and non-SAP applications, allowing remote execution of function modules.
38. What is Authorization in SAP?
Authorization controls what users can access or perform within SAP. Permissions are assigned through Roles, Authorization Objects, and Profiles to ensure secure access.
39. What is SAP Activate Methodology?
SAP Activate is SAP’s implementation framework for SAP S/4HANA. It consists of six phases:
