• What is the cause and solution for SAP error message SRT_WSP760 - Fallback logical port "&1" does not exist ?

  The SAP error message SRT_WSP760 indicates that a fallback logical port specified in your configuration does not exist. This typically occurs in the context of SAP Web Services, particularly when a service is trying to call another service and cannot find the appropriate logical port to use.
  Cause:
  
  Missing Logical Port: The specified fallback logical port is not defined in the system.
  Incorrect Configuration: The logical port may be incorrectly configured or misspelled in the service configuration.
  Transport Issues: If the system has been transported from one environment to another, the logical port may not have been transported correctly.
  Authorization Issues: The user may not have the necessary authorizations to access the logical port.
  
  Solution:
  
  
  Check Logical Port Configuration:
  
  Go to transaction SOAMANAGER.
  Navigate to the Web Service Configuration section.
  Check if the fallback logical port specified in the error message exists. If it does not, you will need to create it.
  
  
  
  Create or Modify Logical Port:
  
  If the logical port does not exist, create a new logical port with the required settings.
  If it exists but is misconfigured, modify it to ensure it has the correct endpoint and settings.
  
  
  
  Verify Naming:
  
  Ensure that the name of the logical port in your configuration matches exactly with what is defined in the system, including case sensitivity.
  
  
  
  Check Transport Requests:
  
  If the system was recently transported, ensure that the logical port was included in the transport request and that it was successfully imported into the target system.
  
  
  
  Authorization Check:
  
  Ensure that the user or service account has the necessary authorizations to access the logical port.
  
  
  
  Fallback Logic:
  
  If you are using fallback logic, ensure that the primary logical port is also correctly configured, as the fallback will only be used if the primary fails.
