SAP ABAP – 用户退出

如果标准 SAP 提取器不提供预期数据或所需功能（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出口。用户出口旨在在标准 SAP 无法满足所有需求时进行一些更改。

为了能够访问每个销售领域的可用退出，请使用以下路径转到 IMG：IMG → 销售和分销 → 系统修改 → 用户退出。SD 领域中每个出口的文档都得到了详尽的解释。

例如，如果您想在销售单据处理（合同、报价单或销售订单）中查找用户退出，请按照上述路径继续展开销售中的用户退出→用户退出节点。单击图标文档以查看销售文档处理中可用的所有用户退出。

用户出口与客户出口的用途相同，但它们仅可用于 SD 模块。出口实现为对功能模块的调用。用户出口是对 SAP 标准程序的修改。
