• What is the cause and solution for SAP error message WRF_CONS151 - Select only one node (one line) ?

  SAP Error Message:
  
  WRF_CONS151: Select only one node (one line)
  
  Cause:
  This error occurs when a user tries to perform an action that requires exactly one node (or one line) to be selected in a hierarchical or tree structure, but either no node or multiple nodes are selected. The system expects a single selection to proceed, and multiple or zero selections violate this requirement.
  Common scenarios include:
  
  Selecting multiple nodes in a tree control where only one node is allowed.
  Trying to execute a function that operates on a single item but the user has selected multiple items.
  Navigating or processing data in a hierarchical structure (e.g., BOM, WBS elements, or organizational units) where the operation is node-specific.
  
  
  Solution:
  
  Select exactly one node or line: Review your selection and ensure that only one node or line is highlighted or selected before proceeding.
  Deselect extra nodes: If multiple nodes are selected, deselect all except the one you want to work with.
  Check the UI controls: Sometimes, the selection mode might allow multiple selections (e.g., using Ctrl or Shift keys). Make sure to select only one.
  Review the process or transaction documentation: Confirm that the function you are trying to execute requires a single node and adjust your selection accordingly.
  
  
  Related Information:
  
  This message is typically encountered in transactions or reports involving hierarchical data structures such as:
  
  Work Breakdown Structures (WBS)
  Bills of Materials (BOM)
  Organizational structures
  Tree views in various SAP modules (e.g., PS, MM, PP)
  
  
  The message is a safeguard to prevent ambiguous processing or errors caused by multiple selections.
  If you are unsure which node to select, consult the business process or ask a functional consultant for guidance.
  If the error persists despite selecting one node, there might be a UI or authorization issue; check with your SAP Basis or security team.
  
  
  Summary:
  
  WRF_CONS151 means you must select exactly one node or line in a hierarchical structure before proceeding. Select only one node to resolve the error.
