SAP ABAP Interview Questions and Answers

1. Introduce yourself

I have around 10+ years of experience working as a SAP ABAP and S/4HANA developer across enterprise landscapes. My core expertise is in ABAP development, OTC processes, pricing enhancements, interfaces and modern S/4HANA technologies such as CDS views, RAP and OData services.

I have worked on RICEF developments including reports, interfaces, conversions, enhancements and forms. My experience also includes integration with external systems using IDocs, BAPIs, RFCs and APIs. Recently I worked on RAP-based OData services and cloud integrations using SAP BTP.

2. What experience do you have in OTC?

OTC stands for Order-To-Cash and it represents the entire business flow from sales order creation until payment is received.

Typical OTC flow:

Customer Inquiry → Quotation → Sales Order → Delivery → Billing → Payment → Accounting posting.

My work in OTC involved:

• Pricing enhancements
• Sales order exits
• Billing forms
• Pricing routines
• IDoc integrations
• Invoice generation
• debugging pricing issues
• reporting for sales and billing data

3. What interfaces have you worked on between SAP and Non-SAP systems?

SAP commonly integrates with external systems.

Common integration mechanisms include:

IDocs
RFC/BAPI
OData APIs
SOAP Web Services
REST APIs
File interfaces (CSV/XML)

Example scenarios:

• sending order data to warehouse systems
• retrieving tax values from external tax engines
• integrating SAP with analytics tools
• exchanging documents with external SaaS systems

4. What is the SAP Pricing Model?

SAP pricing is built using Condition Technique.

Main components include:

Condition Types
Condition Tables
Access Sequences
Pricing Procedures
Condition Records

Condition Types represent pricing elements such as:

Base price
Discount
Surcharge
Freight
Taxes

Pricing procedure determines how these conditions are calculated to derive final price.

5. What is Base Condition Value?

Base condition value is the starting price of a product before discounts or taxes are applied.

Example:

Base Price = 100
Discount = -10
Freight = +5

Final Price = 95

The base value is typically retrieved from condition records maintained in pricing tables.

6. What is Condition Value?

Condition value represents the actual calculated value for a pricing condition.

Examples:

Base Price Condition = 100
Discount Condition = -10
Freight Condition = +5

Each of these is a condition value.

All condition values together determine the final net value of the document.

7. How are Taxes Determined in SAP?

Taxes are determined using pricing conditions.

Tax determination depends on:

Customer Tax Classification
Material Tax Classification
Country and region
Tax condition records

Tax values are calculated based on percentage maintained in condition records.

8. Do you calculate tax internally or through external systems?

It depends on the company architecture.

Two approaches exist:

Internal tax calculation using SAP pricing procedures.

External tax engines such as:

Vertex
Avalara
External government tax APIs

In external systems SAP sends transaction details and receives calculated tax values.

9. Have you worked on interfaces with third party SaaS applications?

Yes.

In enterprise systems SAP often integrates with SaaS platforms for:

Analytics
Finance
Reporting
DevOps tools
Document management systems

SAP sends data through APIs or middleware like:

SAP PI/PO
SAP CPI (Integration Suite)

10. Where do you call the interface from?

The interface is usually triggered from:

User Exit
BADI
Enhancement spot
Custom program
Background job

Example:

Sales Order Save → Call external pricing API

11. How do you call external systems?

Typically through:

REST API
SOAP Web Service
RFC
Middleware Integration

ABAP prepares payload and sends it to external system.

12. How do you populate returned values?

Once SAP receives response:

• parse JSON/XML response
• extract calculated values
• populate SAP structures
• update document fields or pricing conditions

13. Have you worked on OData?

Yes.

OData is used to expose SAP data as REST APIs.

It is mainly used by:

SAP Fiori
External applications
Analytics tools

OData supports operations such as:

Read
Create
Update
Delete

14. Have you developed OData services from scratch?

Yes.

Typical process includes:

Create CDS views or entities
Define service model
Implement backend logic
Expose service as API

These services are consumed by Fiori applications or external systems.

15. What work did you do in Adobe Forms?

I worked on Adobe forms for generating business documents.

Examples include:

Invoice documents
CRF forms
Approval forms
PDF generation

The ABAP driver program collects business data and passes it to the Adobe form interface which generates formatted PDF output.

16. Did you work on OTC process in your projects?

Yes.

The work involved supporting OTC related developments including pricing routines, billing forms, reporting and integrations that support sales order and billing flows.

17. What are User Exits in Pricing?

User exits allow developers to add custom logic in SAP pricing.

Used for:

Custom pricing rules
Conditional discount application
Special calculation scenarios

This avoids modifying SAP standard code.

18. Have you worked on Pricing Routines?

Yes.

Pricing routines are created using VOFM framework.

Types include:

Requirement routines
Condition base value routines
Condition value routines

They help implement complex pricing logic.

19. Difference between Condition Value Routine and Base Value Routine

Base Value Routine determines what amount should be used as the base for calculation.

Condition Value Routine determines how the final condition value should be calculated.

Example:

Base routine → decide base amount
Value routine → calculate final discount value.

20. What technically happens in these routines?

Technically we implement logic inside VOFM routines.

The routine reads pricing structures, evaluates business conditions and returns calculated values back to the pricing engine.

21. What is Equipment in SAP?

Equipment represents a physical asset or machine tracked in SAP.

Used mainly in:

Plant Maintenance
Asset Management

Each equipment record stores information like:

serial number
location
maintenance history
manufacturer details.

22. What did you work on in SAP BTP?

My work involved integration and extensions.

Typical tasks included:

exposing RAP OData services
connecting SAP with cloud applications
building integration flows in BTP Integration Suite
configuring destinations and connectivity

23. Did you create instances in SAP BTP?

Yes.

Service instances are created for services like:

Destination service
Connectivity service
Integration suite

These instances allow cloud applications to connect to backend SAP systems.

24. Did you create service instances in Cloud Foundry?

Yes.

In Cloud Foundry environment:

service instances are provisioned
then bound to applications

Binding allows applications to access credentials and connection configurations.

25. When integrating SAP with a third-party SaaS system that performs calculations, where should the calculation logic reside?

In enterprise architectures the calculation logic should remain in the third-party SaaS system because that system owns the business rules for the calculation.

SAP acts as the transactional system that:

sends required input data
receives calculated values
applies results to SAP business documents

This design keeps systems loosely coupled and avoids frequent SAP code changes when SaaS algorithms change.

26. Where should mapping logic between SAP and third-party SaaS payload be implemented?

Mapping logic is usually implemented in the integration layer such as:

SAP CPI (Integration Suite)
SAP PI/PO
SAP BTP integration flows

Middleware handles:

payload transformation
protocol conversion
field mapping between SAP and external systems

In small integrations mapping can be done directly in ABAP programs, but enterprise systems typically manage mappings in middleware.

27. How do you map calculated values returned from the SaaS system back into SAP?

When SAP receives the response payload (usually JSON or XML), the ABAP program parses the response and extracts the calculated values.

These values are then populated into appropriate SAP structures depending on the business process.

For example:

pricing conditions in sales order
document fields during transaction processing
custom fields in SAP tables

The values are updated before the transaction is saved so that SAP documents reflect the calculated results from the external system.
