BDC使用Batch Input Session来实现BDC

1、【BDC】使用Batch Input Session来实现BDC在ABAP中，我们有两种方法来实现BDC：一种是Batch input session一种是call transaction。先来测试batch input session：它的理论是通过使用session（SM35）来达到bdc的效果，它是分两步走的：第一步是完成BDC数据的组合以及创建session；第二步是Process的session。1.创建session测试程序&-*& Report ZTEST_BDC_1 *& *&-*& Fill BDC table *& *&
