Mat.&1 in prod.supply area &2 is being picked in plant &3 for prod.order

What causes this issue?

Based on information in the contol cycle, material &V1& will be picked
directly for the production order from production supply area &V2& in
plant &V3&.
Therefore, material staging using crate parts is not possible.

How to fix this error?

If you do not want the material to be picked directly for a production
order in the future, maintain the control cycle accordingly.
