Batch Input Processing © SAP AG SAP R/3 Customer data Source file Sequential file Batch input program Batch input function Flight connections Reservation data Batch input or BDC (Batch <strong>Data</strong> Communication) is an automatic procedure for transferring data to the SAP system without a user dialog. A user dialog is simulated for this procedure so that the same checks and updates can be performed. A central component of this procedure is a queue file. This file receives the data via batch input programs and groups associated data together into ‘sessions’. To load the data into SAP databases, you process the sessions with the batch input function (menu options Systems -> Services-> Batch input, Transaction SM35).
Batch Input Program © SAP AG Batch input program BDC table READ DATASET CALL FUNCTION Sequential file Queue file <strong>Data</strong> is transferred to the queue file by batch input programs. These programs perform the following functions: Structure BDCDATA INCLUDE STRUCTURE ABAP/4 Dictionary They provide structured work areas in the form of an internal table (BDC table) for the data to be transferred. They read in the data. They place the data in the BDC table. They transfer the filled BDC table to the queue file. The BDC table receives the input for the data transfer transactions.
