WP404 - Details

• SAP Error Message:
  WP404 - Communication profile does not exist for plant &
  
  
  Cause:
  This error occurs when the system tries to find a communication profile assigned to a specific plant, but no such profile exists or is maintained for that plant. Communication profiles are used in SAP to define how the system communicates with external systems or devices (e.g., for Plant Maintenance, Production, or other integration scenarios). If the profile is missing or incorrectly assigned, the system cannot proceed with the communication or related process.
  
  When does it typically occur?
  
  During integration processes involving plants, such as sending or receiving data via ALE/IDoc, EDI, or other communication interfaces.
  When configuring or executing Plant Maintenance or Production orders that require communication profiles.
  During the setup or execution of workflows or interfaces that depend on plant-specific communication settings.
  
  
  
  Solution:
  
  
  Check if the communication profile exists for the plant:
  
  Use transaction SPRO to navigate to the configuration path where communication profiles are
