  SAP Error Message: VHU01012
  Text: The function you called up is invalid for the line that the cursor is on.
  
  Cause:
  This error occurs when a user tries to execute a function or action on a specific line in a transaction or screen, but that function is not applicable or allowed for the current line where the cursor is positioned.
  Common scenarios include:
  
  The line is in a status or condition that does not permit the requested function.
  The line is empty or does not contain data that supports the function.
  The function is only valid for certain types of lines or entries, and the current line does not meet those criteria.
  The user interface or program logic restricts certain functions based on line attributes or business rules.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the Line Status or Content:
  
  Verify if the line where the cursor is placed contains valid data.
  Ensure the line is in a status that allows the function to be executed.
  
  
  
  Position the Cursor Correctly:
  
  Move the cursor to a line where the function is valid.
  Sometimes, the function is only valid on header lines or specific detail lines.
  
  
  
  Review Business Rules or Custom Logic:
  
  If this is a custom transaction or enhancement, check the coding or user-exits that control function availability.
  Confirm that the function is enabled for the line type or status.
  
  
  
  Consult Documentation or SAP Notes:
  
  Look for SAP Notes related to the transaction or module you are working with.
  Sometimes, patches or updates fix issues related to function availability.

  Ensure users understand which lines support which functions.
  Provide guidance on how to navigate and use the transaction properly.
