attributes for these entries.

stock of product &V2& from the production supply area to the warehouse.

How to fix this error?

Use a separate storage bin for each production supply area
Use the same warehouse process type for all production supply areas that
use the same bin
Alternatively, you can create the warehouse task manually.
