Batch Input Concept

A batch input session is a set of one or more calls to transactions along with the data to be processed by the transactions. The system normally executes the transactions in a session non-interactively, allowing rapid entry of bulk data into an R/3 System.

A session records transactions and data in a special format that can be interpreted by the R/3 System. When the System reads a session, it uses the data in the session to simulate on-line entry of transactions and data. The System can call transactions and enter data using most of the facilities that are available to interactive users.

For example, the data that a session enters into transaction screens is subject to the same consistency checking as in normal interactive operation. Further, batch input sessions are subject to the user-based authorization checking that is performed by the system.

There are three batch input methods:

1. In the Direct Input Method, the programs are provided by the SAP system. These programs are available for Standard Applications. Under this method, the data base is updated using a Function Module, which is responsible for executing the appropriate consistency checks.
2. In the Call Transaction Method, the ABAP Program reads the external data which is present on the Application or Presentation Server, and uses the ABAP Statement CALL TRANSACTION USING to run a SAP statement.
3. In the Session Method the program reads the data and the SAP system stores the data in a “Batch Input Session”. The session records the actions that are required to transfer data into the system using normal SAP transactions.
