• What is the cause and solution for SAP error message /ISDFPS/MM_CS004 - Different ports within an IDoc group ?

  The SAP error message /ISDFPS/MM_CS004 Different ports within an IDoc group typically occurs in the context of IDoc processing, particularly when there is an inconsistency in the ports used for sending or receiving IDocs within a specific IDoc group. This can happen in scenarios where multiple systems or applications are involved in the IDoc communication.
  Cause:
  
  Inconsistent Port Configuration: The error indicates that the IDocs being processed belong to the same group but are being sent or received through different ports. This can happen if the configuration for the IDoc ports is not uniform across the systems involved.
  IDoc Grouping Issues: If IDocs are grouped together for processing, they must all use the same communication port. If one or more IDocs in the group are configured to use a different port, this error will be triggered.
  Incorrect Partner Profile Settings: The partner profiles (WE20) may have been incorrectly set up, leading to different ports being assigned to the same IDoc group.
  
  Solution:
  
  Check Port Configuration: Verify the port settings in transaction WE21. Ensure that all IDocs in the group are configured to use the same port.
  Review Partner Profiles: Go to transaction WE20 and check the partner profiles for the systems involved. Ensure that the ports defined in the partner profiles are consistent and correctly configured.
  IDoc Group Consistency: Ensure that all IDocs that are part of the same group are intended to be processed together and that they are using the same port.
  Reprocess IDocs: After making the necessary adjustments, you may need to reprocess the IDocs that triggered the error. This can be done using transaction BD87 or similar tools for IDoc processing.
  Consult Documentation: If the issue persists, refer to SAP documentation or consult with your SAP Basis or technical team for further troubleshooting.
