• What is the cause and solution for SAP error message /IWBEP/MC_SB_GEN_USR012 - Only one node must be selected ?

  The SAP error message /IWBEP/MC_SB_GEN_USR012: Only one node must be selected typically occurs in the context of SAP Gateway or OData services when a user attempts to perform an operation that requires a single node selection, but multiple nodes are selected instead. This can happen in various scenarios, such as when working with the SAP Fiori apps or when using the SAP Gateway Service Builder.
  Cause:
  
  Multiple Node Selection: The error is triggered when the user tries to select more than one node in a hierarchical structure (like a tree or a list) where only one node is allowed for the operation being performed.
  Incorrect UI Interaction: Users may inadvertently select multiple items due to UI design or misunderstanding of the selection process.
  Service Definition: The OData service may be defined in such a way that it expects a single entity to be processed, but the request includes multiple entities.
  
  Solution:
  
  Select a Single Node: Ensure that you are selecting only one node or entity when performing the operation. Review the UI to confirm that only one item is highlighted or selected.
  Check the OData Service: If you are developing or maintaining the OData service, review the service definition to ensure that it is correctly set up to handle single node selections where required.
  User Training: Provide training or documentation to users to help them understand how to interact with the UI correctly, especially in scenarios where single selections are required.
  Debugging: If you are a developer, you can debug the service to see how the selection is being processed and ensure that the logic correctly handles single node selections.
