VA01-VA03,VA41,VA42,VA43這三個事務代碼的增強直接寫在他們的程序裏面，這裏的增強有點特殊要注意首先要讓他顯示出來，而後才能修改，
程序名：SAPMV45A 增強的點在：include mv45afzb.和include mv45afzz. 雙擊進去後點擊編輯菜單裏面的增強，如下圖：
然後對準裏面的增強點寫相應的代碼。
2.在寫VL01N和VL02N發貨過賬的增強的時候要進去程序相應的點調試然後去找到增強,主要在包含裏面：FV50XF0B_BELEG_SICHERN
3.在寫VF01退出的時候擡頭文本更新時候在包含裏面：MV60AF0B_BELEG_SICHERN，在程序裏面必須等待幾秒才能進行操作，用 WAIT UP TO 2 SECONDS.
4.vl01n點發貨過賬以後的增強點在程序SAPMV50A裏面的es_fv50xf0b_beleg_sichern這裏的第六個增強點
5.VF01點擊保存後的增強點在程序SAPMV60A裏面的enhancement-section beleg_sichern_11 spots es_sapmv60a.
” 把發貨單的擡頭文本和行項目文本帶到發票,此處增強是VL01N直接點擊發貨過賬按鈕的時候執行的
