EWM常规开发知识总结
目录
前言
什么是EWM?
SAP EWM即扩展仓库管理Extended Warehouse Management（简写EWM），此系统为客户处理各种商品移动和管理仓库库存，提供灵活的自动化支持。系统能够对客户所有仓库物流流程进行有计划地高效处理，而仓库中的主要流程是收货和退货，收货和发货。
一、EWM常用tcode/table/function汇总
1.Tcode
EWM直接前台输入的话需要加/n，否则需要在se93执行tcode
| function area | Description | T-code |
|---|---|---|
| Monitor | 仓库管理监控器 | /n/scwm/mon |
| Outbound | 维护出库交货订单 | /n/scwm/prdo |
| Inbound | 维护入库交货 | /n/scwm/prdi |
| Internal | 创建处理单位的仓库任务 | /n/scwm/adhu |

| 维护波次 | /n/scwm/wave | |
| Physical inventory | 创建实际库存凭证 | /n/scwm/pi_create |
| 输入库存盘点计数 | /n/scwm/pi_count | |
| 处理实际库存凭证 | /n/scwm/pi_process | |
| RF | 登录到 RF 环境 | /n/scwm/rfui |

| 资源维护 | /n/scwm/rsrc | |
| 资源组维护 | /n/scwm/rgrp | |
| 描述设备维护 | /n/scwm/prdvc |
2.Table
基本都是以/scwm和/scdl为开头
| Table Area | Description | Table |
|---|---|---|
| Reference | Reference | /SCDL/DB_REFDOC |
| Status | /SCDL/DB_STATUS | |
| Outbound | Outbound Delivery Order Header | /SCDL/DB_PROCH_O |

三、增强
可以通过三种方式查找
1.SE18
SE18->增强点 /SCWM/ES_*
2.SPRO
SPRO->SCM Extended Warehouse Management->扩展仓库管理->
SCM Extended Warehouse Management
3.SE20
SE20->复合增强点/SCWM/ESC_MAIN，显示的所有增强即为EWM可用增强位置
总结
以上就是今天要讲的内容，本文仅仅简单介绍了EWM常用的常规开发知识，也是我在项目上积累所得，具体的开发还需上手实操。
