SAP ABAP 用戶退出

如果標準SAP提取器不提供期望的數(shù)據(jù)或所需的功能，例如在授權或時間檢查中，則在提取中使用用戶出口。 用戶出口通常用于銷售和分銷(SD)模塊。 SAP在銷售，運輸，運輸和計費領域提供了許多退出。 用戶出口旨在在標準SAP無法滿足所有要求時進行一些更改。

要能夠訪問每個銷售區(qū)域中可用的退出，請使用此路徑轉(zhuǎn)到IMG:IMG → Sales and Distribution → System Modifications → User Exits。 將詳細解釋SD區(qū)域中每個出口的文檔。

例如，如果要在銷售憑證處理(合同，報價或銷售訂單)中查找用戶退出，請按照上述路徑繼續(xù)展開銷售中的Sales → User Exits。 單擊圖標文檔以查看銷售憑證處理中提供的所有用戶退出。

用戶出口的功能與客戶退出功能相同，但它們僅適用于SD模塊。 退出實現(xiàn)為對函數(shù)模塊的調(diào)用。 用戶退出是對SAP標準程序的修改。
