BAPIs

Quick answer

BAPIs are the reference catalogue of safe, supported operations on SAP objects, essential for integration and data loads.

Key takeaways

  • Use the BAPI Explorer (transaction BAPI) to browse by business object.
  • View the underlying function module in SE37.
  • Check parameters and the RETURN structure.
  • Watch out: Guessing instead of using the reference tools.

What it is

A BAPI (e.g. BAPI_SALESORDER_CREATEFROMDAT2) is a released function module representing an operation on a business object, enforcing SAP’s business logic. BAPIs are documented, stable across releases and callable remotely, the safe programmatic API for classic integration.

How to find/use it

  • Use the BAPI Explorer (transaction BAPI) to browse by business object.
  • View the underlying function module in SE37.
  • Check parameters and the RETURN structure.
  • Remember: check RETURN and call BAPI_TRANSACTION_COMMIT.

Why it matters

BAPIs are the reference catalogue of safe, supported operations on SAP objects, essential for integration and data loads. Knowing the right BAPI (and its commit/return rules) avoids risky direct table writes.

Common pitfalls

  • Guessing instead of using the reference tools.
  • Editing/using without understanding the object.
  • Relying on memory for details you can look up.
