如何快速从BSEG读取数据(转)

由于bseg表很大，而且表的索引字段是：

BUKRS - Company Code

BELNR - Accounting Document Number

GJAHR - Fiscal Year

BUZEI - Line Item Number

 访问此表最佳的是包含所有的索引字段，但在实际应用是很少能达到的。但要有好的性能根据经验必须要有公司和凭证号作为查询条件。为了达到这一点，我可以根据条件不同而使用不同ｓａｐ的其他表，先查出公司和凭证号，再去读取ＢＳＥＧ表。

代码如下：

注意：该程序包含了各种条件的查询，程序员可以根据自己应用需求选择对应一个的子程序来读取公司和凭证号。
