The system has attempted to reroute therelationships of these phases to their predecessors or successors. Thisled to a situation that made it necessary to terminate the rerouting ofthese relationships.

System Response
For some of the missing phases no new relationships were generated. Itcannot be guaranteed that a correct PPM will be generated in APO.

Procedure
