Dear all ,
As bellow screenshot , the red highlight component material is the phantom item in work order.
The storage location 'T01P' is assigned to MRP area 'CS1000' , the material master is also maintained
But this material requirment is in Plant MRP area '1000' , not in MRP area 'CS1000':
The other non-phantom components in the same work order are right , all display in MRP area 'CS1000'.
And the components under the phantom materail are also right.
So i am confused why phantom item materials are not right . Please give me the direction , thanks!

On your screenshot you can observe that all the MRP elements are under a special stock segment called "planning without assembly". This is a standard behavior for this planning strategy and, unfortunately, this stock segment is not supported under the MRP areas, so it is always displayed under the plant.
In summary, your system is working as designed.
