• What is the cause and solution for SAP error message W8305 - Select a line area first ?

  SAP Error Message:
  
  W8305 - Select a line area first
  
  Cause:
  This warning message typically appears in SAP when you attempt to perform an action that requires a line item or a specific area within a list or table to be selected first, but no line or area has been selected. For example, in transaction codes involving line item processing (such as sales orders, purchase orders, or billing documents), certain functions (like change, delete, or display details) require the user to highlight or select a particular line before proceeding.
  
  When does it occur?
  
  When you try to execute an operation on a list or table without selecting any line.
  In screens where multiple line items are displayed, and the system expects the user to select one or more lines before continuing.
  Common in document processing transactions (SD, MM, FI modules).
  
  
  Solution:
  
  Select a line item or area first: Before performing the action (e.g., change, delete, display), click on the line or checkbox corresponding to the item you want to work with.
  Check the screen layout: Ensure that the list or table is active and that you have properly selected the line.
  If using keyboard navigation: Use arrow keys or other navigation keys to highlight the line.
  If the issue persists: Verify if the screen or transaction has any custom enhancements or user exits that might affect line selection behavior.
  
  
  Additional Information:
  
  This is a warning message (W), so it usually prevents the action until a line is selected.
  The message text can be found in transaction SE91 by entering message class W83 and message number 05.
  The message is part of standard SAP GUI behavior to ensure users explicitly select the data they want to manipulate, preventing accidental changes.
  If you are developing or customizing SAP screens (e.g., using ABAP List Viewer ALV), ensure that the selection logic is properly implemented to avoid this message.
