* Description : *
* *
* 1. Read input file *
* 2. Check the mandatory fields and if any one of them is missing *
* move the record to error file. *
* 3. Fill the bdcdata and call F-02 transaction *
* 4. If any errors format the message and send it for reporting *
* 5. If any errors, it downloads the error file *
* 6. Based on user input, this programs does the follwoing *
* a).Call transaction and in case of errors add to a session *
* B).Create session *
* 7. Display the Audit report *
