Fundamentals, definitions and simple scenarios. Good for freshers and warm-ups.
1. What is ERP, and why do companies use it?
Answer flow · 4 steps
1
Enterprise resource planning software brings a company's core processes, such as finance, purchasing, inventory, sales, production and HR, into one system with a shared database.
2
Instead of separate spreadsheets and tools, a sales order automatically updates stock, triggers delivery and posts to accounts.
3
This gives a single source of truth, real-time reporting and better control.
4
SAP, Oracle, Microsoft Dynamics and Tally (for smaller businesses) are common examples.
2. What is the difference between ERP and CRM?
Answer flow · 4 steps
1
ERP manages internal operations: finance, inventory, procurement, production and HR.
Salesforce, HubSpot and Zoho CRM are CRMs; SAP S/4HANA and Oracle ERP are ERPs.
4
The two are often integrated so that a deal won in the CRM becomes a sales order in the ERP.
3. Explain the order-to-cash (O2C) process.
Order to cash covers everything from a customer order to receiving payment: the sales order is created, credit and availability are checked, goods are picked, packed and delivered, the invoice is raised, and the payment is received and matched to the invoice. In SAP this flows through the SD module for order, delivery and billing, and into FI for accounts receivable.
4. Explain the procure-to-pay (P2P) process.
Answer flow · 4 steps
1
Procure to pay starts with a purchase requisition, which becomes a purchase order to a vendor.
2
When goods arrive, a goods receipt is posted, which updates inventory.
3
The vendor invoice is checked against the purchase order and goods receipt (three-way match) and then paid.
4
In SAP this runs through MM and posts to FI accounts payable.
5. What is the difference between master data and transactional data?
Answer flow · 3 steps
1
Master data is relatively stable core data used across processes, such as customers, vendors, materials, employees, GL accounts and prices.
2
Transactional data records business events, such as sales orders, purchase orders, invoices, goods movements and payments, which refer to master data.
3
Poor master data quality causes errors across every process, so it needs governance.
6. Which modules does a typical ERP system have?
Finance and accounting, controlling or cost accounting, sales and distribution, purchasing (materials management), inventory and warehouse management, production planning and manufacturing, quality management, plant maintenance, project systems, human resources and payroll, and analytics. Modules share one database, so a transaction in one updates the others automatically.
7. What is the difference between a functional and a technical consultant?
Answer flow · 3 steps
1
A functional consultant understands business processes in an area such as finance or sales, gathers requirements, configures the system, writes functional specifications, tests and trains users.
2
A technical consultant develops custom programs, reports, interfaces, forms and enhancements, for example in ABAP or Apex, and handles integrations and data migration programs.
3
Both work closely together.
8. What is the difference between cloud and on-premise ERP?
On-premise ERP runs on the company's own servers, giving full control and customisation but requiring investment in hardware, IT staff, upgrades and security. Cloud ERP, such as SAP S/4HANA Cloud, Oracle Fusion, Microsoft Dynamics 365 or NetSuite, is hosted by the vendor with subscription pricing, automatic updates, faster implementation and easier scaling, with less freedom to customise.
9. What is the record-to-report process?
Record to report covers collecting, processing and reporting financial data: recording journal entries from all business processes, managing the general ledger, reconciling accounts, handling fixed assets and inter-company transactions, performing period-end closing, consolidating results, and producing financial statements and management reports.
10. What is the hire-to-retire process?
Hire to retire covers the employee lifecycle in HR systems: workforce planning, recruitment and hiring, onboarding, organisational management, time and attendance, payroll, benefits, performance and learning management, transfers and promotions, and finally exit or retirement with settlement. Systems such as SAP SuccessFactors and Workday support it.
Applied problems, trade-offs and questions about your own projects.
11. What are the phases of an ERP implementation?
Using SAP Activate as an example: Discover and Prepare (scope, team and plan), Explore (fit-to-standard workshops to compare business processes with the standard system and identify gaps), Realize (configuration, development, data migration and testing), Deploy (user training, cut-over and go-live) and Run (hypercare and ongoing support). Most failures come from poor requirements, too much customisation, bad data and weak change management, not from the software itself.
12. What is the difference between configuration and customisation?
Answer flow · 3 steps
1
Configuration uses the system's built-in settings to fit a process, for example defining company codes, document types or approval rules, without writing code.
2
Customisation means writing code or building new objects, such as ABAP programs or Apex classes, when the standard system cannot meet a requirement.
3
I prefer configuration because customisations cost more to test, maintain and upgrade.
13. How do you handle data migration into a new ERP or CRM?
Answer flow · 3 steps
1
I identify what data to migrate (master data such as customers, vendors and materials, plus open transactions and opening balances), cleanse it by removing duplicates and fixing formats, and map old fields to new ones.
2
I run trial loads in a test system with tools like the SAP Migration Cockpit or Salesforce Data Loader, and reconcile record counts and totals with the business.
3
The final load happens during cut-over, followed by sign-off.
14. How do you gather requirements from business users?
Answer flow · 3 steps
1
I run workshops with process owners and walk through their current process step by step, including exceptions.
2
I ask for real documents and reports, separate must-haves from nice-to-haves, and write requirements as user stories or a functional specification with acceptance criteria.
3
I show the standard system early (fit-to-standard) so users judge something concrete rather than describing an ideal in the abstract.
15. What is a fit-gap analysis?
Answer flow · 3 steps
1
In a fit-gap (or fit-to-standard) analysis, consultants walk business users through standard system processes and compare them with business requirements.
2
Fits are met by standard functionality or configuration, and gaps need a decision: change the business process to fit the standard, accept a workaround, or build an extension.
3
Minimising gaps reduces cost and simplifies upgrades.
16. How is user acceptance testing done in ERP projects?
Answer flow · 3 steps
1
Business users test end-to-end scenarios, such as order to cash or procure to pay, using realistic data in a quality system, following test scripts prepared with consultants.
2
Defects are logged, fixed and retested, and integration with other systems is checked.
3
UAT ends with formal business sign-off confirming the system is ready for go-live.
17. What is cut-over planning?
Answer flow · 3 steps
1
Cut-over is the move from the old system to the new one at go-live.
2
The cut-over plan lists every task with owners, timings and dependencies: freezing transactions in the old system, migrating and validating master data, open items and balances, moving configuration and code to production, final checks, user access, go or no-go decision points and a rollback plan.
3
It is rehearsed in mock cut-overs.
18. Why is change management important in ERP implementations?
ERP projects change how people work, and many failures come from user resistance rather than technology. Change management involves leadership sponsorship, early communication about why the change matters, involving key users in design and testing, role-based training, super users who support colleagues, clear support after go-live, and measuring adoption.
19. How do you measure the success of an ERP implementation?
Measure against the goals in the business case, such as faster month-end close, lower inventory, fewer manual errors, shorter order-to-delivery time, better on-time payments, user adoption rates, reduction in support tickets over time, and data accuracy. Measuring a baseline before go-live is essential to show the improvement.
20. Which types of testing are done in an ERP project?
Unit testing of each configuration and development, integration testing of end-to-end processes across modules and interfaces, data migration testing, regression testing after changes, performance testing for heavy processes such as month-end or payroll runs, security and role testing, and user acceptance testing by the business. Automated testing tools speed up regression for frequent updates.

System design, deep internals, leadership and tough follow-ups.
21. How do you integrate an ERP with other systems?
Answer flow · 3 steps
1
I agree which system owns each piece of data, then choose the method: REST or SOAP APIs, SAP IDocs and BAPIs, OData services, or middleware such as SAP Integration Suite, MuleSoft or Boomi for many systems.
2
I design for failure with retries, error queues, logging and alerts, make interfaces idempotent so duplicates are not created, and secure them with proper authentication.
3
Volume and real-time needs decide whether to use events or scheduled batches.
22. How do you manage roles and security in an ERP or CRM?
Answer flow · 4 steps
1
I design roles around job functions and grant the least access each needs.
2
I enforce segregation of duties so one person cannot, for example, create a vendor and also pay it.
3
In SAP that means roles and authorisation objects; in Salesforce, profiles, permission sets, role hierarchy and sharing rules.
4
I review access regularly, remove leavers promptly and keep audit logs for compliance.
23. A critical production issue stops invoices from posting. How do you handle it?
Answer flow · 4 steps
1
I confirm the impact and urgency, inform stakeholders and log a priority ticket.
2
I reproduce the error, read the message and logs, and check what changed recently: transports, configuration, master data or an interface.
3
I find a quick workaround to unblock the business if possible, fix the root cause in development, test it and move it through the proper change process.
4
Afterwards I write up the root cause and how we will prevent it.
24. What is the difference between SAP ECC and SAP S/4HANA?
Answer flow · 3 steps
1
S/4HANA is SAP's current ERP and runs only on the in-memory HANA database, while ECC ran on several databases and reaches end of mainstream maintenance in 2027.
2
S/4HANA has a simpler data model (for example the Universal Journal, table ACDOCA, combines finance and controlling), Business Partner replacing separate customer and vendor masters, real-time analytics and the Fiori user interface.
3
It can be run on-premise or in the cloud.
25. How does SAP Activate combine agile and ERP implementation?
Answer flow · 3 steps
1
SAP Activate structures projects into Discover, Prepare, Explore, Realize, Deploy and Run phases.
2
It starts from SAP Best Practices and fit-to-standard workshops, then builds and tests in iterative sprints during Realize with frequent business reviews, while keeping governance, quality gates and integrated planning.
3
It suits the clean core approach for S/4HANA projects.
26. How is post-go-live support organised?
Answer flow · 3 steps
1
Immediately after go-live, a hypercare period of several weeks provides intensive support from the project team.
2
Then a support model takes over: L1 support (help desk and super users) handles basic questions, L2 (functional consultants) solves configuration and process issues, and L3 (technical experts or the vendor) fixes complex defects.
3
Tickets are tracked with priorities and service level agreements.
27. Why do ERP implementations fail, and how do you rescue one?
Common causes are unclear requirements and scope creep, too much customisation, poor data quality, weak leadership support, insufficient testing and training, and unrealistic timelines. To rescue a project, assess the real status, reset scope to what is essential, strengthen governance and the project team, fix data and testing, re-plan realistically and communicate honestly with stakeholders.
28. How is AI being used in ERP and CRM systems?
Answer flow · 3 steps
1
Vendors are adding AI assistants and agents, such as SAP Joule, Salesforce Agentforce, Microsoft Copilot in Dynamics 365 and Oracle AI agents, which answer questions in natural language, summarise records, draft emails and documents, and automate tasks.
2
AI also powers invoice matching, cash application, demand forecasting, anomaly detection and lead scoring.
3
Data quality and access controls remain essential.
29. How do you design approval workflows in business software?
Map the business rules first: which documents need approval (purchase requisitions, orders, invoices, discounts or leave), based on amount, cost centre, category or risk, who approves at each level, substitutes when approvers are away, escalation times and notifications. Configure them with the system's workflow tools, keep them as simple as possible, ensure segregation of duties and test edge cases.
30. How do you roll out an ERP template globally with local requirements?
Design a global template with standard processes, data structures and reporting for all countries, then add localisations for each country: tax rules (such as GST and e-invoicing in India), statutory reports, languages, currencies, payroll and banking formats. Roll out in waves, reuse the template, allow local changes only where legally or commercially required, and govern the template centrally.
