If you have assigned the plant or storage location to a warehouse number
in Logistics Execution that is already assigned to another plant or
storage location, the system cannot determine any data for the plant or
the storage location. You can assign only one storage location to a
warehouse. Remove the assignment in the <LS>Assign Warehouse Number to
Plant and Storage Location</> configuration step. Find this
configuration step under <LS>Manage Your Solution </>> <LS>Configure
Your Solution </>> <LS>Organization </>> <LS>Assign Warehouse Number to
