When a company decides to implement the SAP R/3 to manage business critical data, it usually does not start from a no-data situation. Normally, a SAP R/3 project comes into replace or complement existing application. In the process of replacing current applications and transferring application data, two situations might occur:
- The first is when application data to be replaced is transferred at once, and only once.
- The second situation is to transfer data periodically from external systems to SAP and vice versa.
- There is a period of time when information has to be transferred from existing application, to SAP R/3, and often this process will be repetitive.
The SAP system offers two primary methods for transferring data into SAP systems. From non-SAP systems or legacy system. These two methods are collectively called “batch input” or “batch data communication”.
- SESSION METHOD
- CALL TRANSACTION
- DIRECT INPUT
