  The SAP error message /PF1/MSG_BPC_LAYER309 Communication failure for Parallel Process typically indicates that there is a communication issue when trying to execute a parallel process in SAP Business Planning and Consolidation (BPC). This can occur due to various reasons, including network issues, configuration problems, or resource limitations.
  Causes:
  
  Network Issues: Temporary network disruptions can lead to communication failures between the BPC application server and the database or other services.
