VF01/VF02/VF03屏幕增强及BAPI增强字段处理
1.在销售发票抬头表中增加增强字段
2.创建处理程序
主程序SAPMV60A中的所有包含文件都是以MV60AF打头的，所以我们创建一个独立的程序 SE38(ZSDU0001) 来存放所有的处理代码
创建屏幕9001,确保屏幕类型为子屏幕
屏幕字段可从VBRK表中获取

3.屏幕增强
在主程序SAPMV60A 的 屏幕6001中 双击 CUST_HEAD_ACTIVATE 直到对应的FORM
显示隐式增强->创建实施->使用 PERFORM … IN PROGRAM … IF FOUND 创建增强
FORM涉及详细的逻辑代码,在ZSDU0001程序中编写,在上边
ENHANCEMENT 1 ZE_SAPMV60A. "active version
PERFORM cust_head_activate IN PROGRAM zsdu0001 IF FOUND
USING vbrk vbuk xvbpa[]
CHANGING gs_cust_tab-head_caption
gs_cust_tab-head_program
gs_cust_tab-head_dynpro
tabstrip_tab06.
ENDENHANCEMENT.
业务加载项BADI_SD_CUST_HEAD的另外三个方法是用在屏幕6101中，建议不管当前是否有使用到，都应当进行增强到程序ZMV60AFZCUST_HEAD中以预留将来可以方便的修改，所有的增强实施都应当使用同一个名称ZE_SAPMV60A，这样我们可以方便地使用SE20查看所有的增强
perform cust_head_set_data->(FORM涉及详细的逻辑代码,在ZSDU0001程序中编写,在上边)

用VF02修改发票凭证，转到抬头–>抬头增强字段，填写相关的数据并保存，然后检查表VBRK发现增强字段已经保存成功
用VF03查看发票凭证,发现页签是只读格式,创建增强字段成功
以上为抬头屏幕增强,行项目增强在6002屏幕上
