用户退出

如果标准SAP提取器不提供期望的数据或所需的功能，例如在授权或时间检查中，则在提取中使用用户出口。 用户出口通常用于销售和分销(SD)模块。 SAP在销售，运输，运输和计费领域提供了许多退出。 用户出口旨在在标准SAP无法满足所有要求时进行一些更改。

要能够访问每个销售区域中可用的退出，请使用此路径转到IMG:IMG → Sales and Distribution → System Modifications → User Exits。 将详细解释SD区域中每个出口的文档。

例如，如果要在销售凭证处理(合同，报价或销售订单)中查找用户退出，请按照上述路径继续展开销售中的Sales → User Exits。 单击图标文档以查看销售凭证处理中提供的所有用户退出。

用户出口的功能与客户退出功能相同，但它们仅适用于SD模块。 退出实现为对函数模块的调用。 用户退出是对SAP标准程序的修改。
