PP-WM Interaction

hi experts,

when i go for process order creation, i get storage location as PM01 as default for one material.

It lies in PM02 and is extended for both storage location PM01 and PM02.

For material,WM and supply area is extended for both the storage locations.

My problem is that when i go for WM material staging it gives error and auto TR not done.

Plz Help me
