• What is the cause and solution for SAP error message FDT_EXPRESSIONS361 - Only one default branch is allowed per gateway (Gateway &1) ?

  The SAP error message FDT_EXPRESSIONS361 indicates that there is an issue with the configuration of a decision branch in a gateway within the SAP system. Specifically, it states that only one default branch is allowed per gateway, and it identifies the gateway in question with the placeholder &1.
  Cause:
  This error typically occurs when you have defined multiple default branches in a decision structure (like a switch-case or if-else structure) within a gateway. In programming logic, a default branch is meant to handle cases that do not match any of the specified conditions.

  Solution:
  To resolve this error, you should:
  
  
  Review the Gateway Configuration: Go to the configuration of the gateway mentioned in the error message. Check the decision branches defined within it.
  
  
  Identify Default Branches: Look for any branches that are marked as default. You should only have one default branch.
  
  
  Remove or Modify Extra Default Branches: If you find multiple default branches, you need to either:
  
  Remove the extra default branches.
  Modify the logic to ensure that only one branch is designated as the default.
  
  
  
  Test the Configuration: After making the necessary changes, test the gateway to ensure that it functions correctly without triggering the error.
  
  
  Documentation: Document the changes made for future reference and to help other team members understand the configuration.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on configuring gateways and decision branches.
  SAP Community: You can search for discussions or similar issues in the SAP Community forums, where other users may have encountered and resolved the same error.
