• What is the cause and solution for SAP error message SRT_WSP780 - Logical port '&1' is already assigned to proxy '&2' ?

  The SAP error message SRT_WSP780 indicates that a logical port is already assigned to a proxy service, which means that the system is trying to assign the same logical port to another proxy or service, leading to a conflict. This typically occurs in scenarios involving web services and service-oriented architecture (SOA) where logical ports are used to define the connection settings for web service communication.
  Cause:
  
  Duplicate Assignment: The logical port you are trying to assign is already in use by another proxy service.
  Configuration Error: There may be a misconfiguration in the service definitions or logical ports.
  Development or Transport Issues: If changes were made in a development environment and transported to a production environment, there might be inconsistencies in the logical port assignments.
  
  Solution:
  
  
  Check Existing Assignments:
  
  Go to the transaction code SOAMANAGER.
  Navigate to the "Web Service Configuration" section.
  Check the existing logical ports and their assignments to ensure that the logical port you are trying to use is not already assigned to another proxy.
  
  
  
  Reassign or Create a New Logical Port:
  
  If the logical port is indeed in use, you can either:
  
  Reassign the existing logical port to the correct proxy if it was incorrectly assigned.
  Create a new logical port for the new proxy service if you need to keep both.
  
  
  
  
  
  Review Proxy Configuration:
  
  Ensure that the proxy service is correctly configured and that there are no conflicting settings.
  Check the service definitions and ensure that they are correctly set up to use the intended logical ports.
  
  
  
  Transport Issues:
  
  If this issue arose after a transport, verify that the transport did not overwrite any existing configurations that could lead to this conflict.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to web service configuration and logical ports for additional guidance.
