No accountable force element found for object &1

What causes this issue?

The force element with the object number &V1& was assigned to a new
force element as a subordinate element. This means that the stockholding
storage location in this force element must be assigned to a new MRP
area, that is, the MRP area of the new accountable force element. The
system was unable to find the new superior force element in the new
hierarchy path.

System Response

You cannot change the assignment of the storage location to the MRP
area. This results in inconsistencies between the organizational
structure and the mapping of the structures in Materials Management.

How to fix this error?

Check the organizational structure and define an accountable element
with its own MRP area in the new path of the force element. Assign the
storage location to this MRP area.
