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 |

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
