增强方式：替代，【替代基本用在FICO模块】
BTE增强方式应用更广，需要学习总结。
程序：ZRGGBS*
步骤 1，SE16N:GB01 将 ZBD1T排除标记置为空，【注意，此更改跨client,dev700 修改，test710 也被修改】
通 ZTERM
排除
9 S BSEG ZBD1T X
9 S BSEG ZTERM
2.替代程序RGUGBR00 重新运行；
应用领域 *
调用点 *
使用标准变式：SAP&OIBSEGBKPF
运行结果：成功完成存储和生成
消息号 GB000
3.程序zrggbs000 代码增强

*替代付款方式：BSEG-ZTERM
*1.系统根据BSEG-BUKRS（公司代码）=（CV50，CV51，CV52），
* BSEG-KOART（科目类型）=K，
* 根据BSEG-LIFNR（供应商账号）到LFB1-LIFNR=BSEG-LIFNR，
* LFB1-BUKRS=BESG-BUKRS（公司代码），找到LFB1-ZTERM赋值给BSEG-ZTERM
