SAP

Enterprise resource planning (ERP) software used by large corporations to manage finance, supply chain, HR, and operations.

SAP is the dominant ERP platform at large enterprises, used to integrate and manage core business processes — financial accounting, procurement, manufacturing, supply chain, and HR — in a single system. SAP skills are required at finance, supply chain, and operations roles at large corporations and command significant salary premiums given the system's complexity.

Typical time to job-readiness: ~3 months.

Learning SAP

Beginner

Navigate the SAP interface, understand transaction codes, and learn the basic data model for your specific module (FI, MM, SD, or HR) — most SAP users specialize in one.

Intermediate

Run end-to-end business processes within your module, work with master data, and generate standard reports. SAP is learned primarily through repetition and on-the-job exposure.

Advanced

System configuration, role and authorization management, and leading SAP implementations or S/4HANA migrations. SAP expertise typically develops over years in large enterprise environments.

Key concepts

  • Modules: FI (Finance), MM (Materials Management), SD (Sales & Distribution), HR — SAP users typically specialize in one
  • Transaction codes (T-codes) — shortcuts to navigate SAP screens (e.g., ME21N to create a PO)
  • Master data vs transactional data — material master and vendor master vs purchase orders and invoices
  • Integration — SAP modules share a single database, eliminating data silos between finance, procurement, and logistics
  • ABAP — SAP's proprietary programming language for customization and reports
  • S/4HANA — SAP's modern cloud ERP, successor to ECC; most organizations are mid-migration

Common interview topics

  • What SAP modules have you worked in and what were your responsibilities
  • Explain the procure-to-pay process in SAP
