Hi Gopi
Check Processing tab in ECC for your del header.
Field >>Dec. whse B Distributed is EWM or any decentralized wh. and if its not the not relevant.
| Not Relevant | |
| A | Relevant |
| B | Distributed |
| C | Confirmed |
| D | Planned for Distribution |
| E | Delivery split was performed locally |
| F | Change Management Switched Off |
2. if your del you can changed in vl32n or vl02n then its ecc and if you cant change it means it ewm.
