  SAP Error Message: VHU01054
  Text:
  
  Select exactly one existing item before executing this function
  
  Cause:
  This error occurs when a user tries to execute a function or action in a SAP transaction (often related to Vehicle Management or similar modules) that requires exactly one item to be selected from a list or table, but either:
  
  No item is selected, or  
  More than one item is selected.
  
  The system expects a single, unique selection to proceed with the requested operation, but the current selection does not meet this requirement.
  
  When does it typically occur?
  
  In vehicle management transactions (e.g., Vehicle History, Vehicle Usage, or Vehicle Master Data screens) where you have a list of items (vehicles, documents, etc.) and you want to perform an action like display, change, or delete.  
  When a function key or button is pressed that requires a single item context.
  
  
  Solution:
  
  
  Select exactly one item:
  
  Before executing the function, ensure that you select exactly one item from the list or table.  
  
  If no item is selected, click on the checkbox or highlight the row of the item you want to work with.  
  If multiple items are selected, deselect all but one.
  
  
  
  Check the selection method:
  
  Sometimes, the selection might be done via checkboxes, or by highlighting a row. Make sure you are using the correct method as required by the transaction.
  
  
  Refresh the screen:
  
  If the selection seems correct but the error persists, try refreshing the screen or reloading the data to ensure the UI is synchronized.
  
  
  Review user authorization:
  
  In rare cases, insufficient authorization might cause the system to not recognize the selection properly. Verify that the user has the necessary permissions.
  
  
  
  Additional Information:
  
  
  Message Class: VHU (Vehicle Management)  
  
  
  Message Number: 01054  
  
  
  This message is a standard validation message to prevent ambiguous operations on multiple or no items.
  
  
  If you are developing or customizing SAP screens or reports, ensure that the code checks for exactly one selected item before proceeding with functions that require a single context.
  
  
  
  Example:
  If you are in a vehicle list screen and want to display details of a vehicle, you must select one vehicle from the list. If you press the "Display" button without selecting any vehicle or after selecting multiple vehicles, the system will throw this error.
