BDC (Batch Data Conversion) is an automated procedure. It transfers a large volume of external or legacy data into an SAP system using batch input programming. The following are 3 ways of achieving this.
* Call Transaction Method
* Session Method
* Direct Input Method
Irrespective of the method, the techniques use the following steps
* Identify the screen of transactions that the program will process.
* Write a program to build the BDC table that will be used to submit the data (text file) to SAP.
* Finally, submit the BDC Table to the system. Use the “ batch mode” or a “single transaction” by the CALL TRANSACTION command.
The Call Transaction method cannot be used when you want to process multiple transactions. Instead, use the BDC-insert function to achieve this.
