  The SAP error message PAK705, which states "There can be only one active system for determining the interface," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO). This error indicates that the system is trying to determine an interface for a message, but there is more than one active system configured for that purpose, which leads to ambiguity.
  Cause:

  Deactivate Unused Systems:
  
  If there are multiple systems that are not needed, consider deactivating or removing them from the configuration to eliminate the conflict.
  
  
  
  Check for Duplicate Entries:
  
  Look for any duplicate entries in the configuration that might be causing the system to see multiple active interfaces.
