Introduction

• One of the important challenges in a SAP implementation is its integration with other systems in the enterprise; another one is WEB enabling some of its functionalities.

• SAP provides a basic infrastructure for integrations that is secure, efficient and transparent.

Advantages

Data is created in real-time in SAP. User friendly screens without extraneous fields. Minimal training time. Knowledge of how to navigate in SAP is not

required.

Examples

• Import/Export Data: In this application We read data from different modules of SAP, Save it in a local database, generate data equivalences and export it to other systems in a pre defined format.

• Monetary Adjustment: Reads balance sheet data from SAP, calculates the monetary adjustment based on rules introduced in the application, and writes back the GL entry to SAP via BAPI call.

• Purchase Order for Transport Service: Reads transport operations registered in SAP (IS-OIL), aggregates contract conditions, generates the conciliation sheet, generates the SAP PO of the service, and liberates it.

Conclusion

• Although SAP is intended to cover all activities in the enterprise other auxiliary or activity specific systems will exist and for that integration with SAP is essential.

• ABAP is the official programming language of SAP, but every thing that can be done in ABAP also can be done in other programming languages using RFC and BAPIs.
