Example of program for Batch Input and  Call Transaction

This example shows how to use Call Transaction. If Call Transaction fails,

a batch input session is created.

DATA: BEGIN OF BDC_TAB OCCURS 0.
        INCLUDE STRUCTURE BDCDATA.
DATA: END OF BDC_TAB.

FORM Create_Transaction.
* Table for messages from call transaction. The table is automatically
* filled with messags from call transaction.

  DATA END OF messtab.
