# SAP EWM and TM: see where warehouse work and transport wait

Read embedded EWM warehouse work and TM freight orders with your SAP S/4HANA source, to see where receiving, putaway, picking, shipping and transport wait.
## What does Duaer read?

- Warehouse (EWM): each EWM delivery is a case. Inbound gives Received and Put away, outbound Picked and Shipped, from confirmed warehouse tasks and posting times.
- Transportation (TM): each freight order is a case: Planned (created), Shipped (actual departure) and Received (actual arrival). Canceled orders and events are left out.
- Both match the inventory and supply chain template.

## How do you set it up?

1. In SAP, add communication arrangements for API_WAREHOUSE_ORDER_TASK_2, API_WHSE_INBOUND_DELIVERY_2 and API_WHSE_OUTBOUND_DELIVERY_ORDER_2 (warehouse) or API_FREIGHTORDER (transportation) to the communication user.
2. As an owner or admin, open Data sources, select Add source, choose SAP S/4HANA Warehouse (EWM) or Transportation (TM) under Inventory and supply chain, choose the SAP S/4HANA credential, select Check system and confirm. Only the processes the user may read are offered.

## How often does it read, and how much?

Each run reads a time window by confirmation or change time; a first read starts a year back. A step is never written twice. Read only.

## What are the limits?

- The tables, entities and fields read follow the vendor's published documentation and are not yet checked against a real system; the first real read may need adjustments.
- Embedded EWM and TM in S/4HANA only, not standalone SAP EWM or SAP TM.
## Questions

### Do I need a new credential?

No. Use the SAP S/4HANA credential you already have; add the communication arrangements of these APIs to its user.
