Minimum stock level per warehouse and MRP

Hello experts

We have tested minimum stock level per warehouse and try to use it for the MRP but it seems that the MRP uses for a specific warehouse the consolidated minimum level

For example

WSE 1 minimum stock level 10

WSE 2 minimum stock level 5

MRP runs for WSE 2 recommandation is calculated based on 15 pieces of minimum stock level (WSE 1+2)

Could you please tell me if this is normal behavior and the use of minimum stock level per warehouse is not possible ?
