• What is the cause and solution for SAP error message W_CB140 - Select a line ?

  SAP Error Message:
  
  W_CB140 - Select a line
  
  Cause:
  The message W_CB140 "Select a line" typically appears in SAP when a user is expected to select a line item from a list or table but has not done so. This is a warning message prompting the user to make a selection before proceeding.
  This often occurs in transaction screens or reports where multiple entries are displayed, and the system requires the user to explicitly select one or more lines to perform an action (e.g., edit, delete, display details).
  
  When does it occur?
  
  When you try to execute an action that requires a line selection but no line is selected.
  In list processing screens, such as in logistics, finance, or HR modules.
  During processing of batch jobs, workflows, or mass changes where line selection is mandatory.
  
  
  Solution:
  
  Select a line: Simply click on the checkbox or highlight the line item you want to process.
  Check the screen: Look for selection options such as checkboxes, radio buttons, or row highlights.
  If no lines are available: Verify that the list is populated correctly. If the list is empty, check the selection criteria or data availability.
  If the issue persists:  
  
  Check if there is a user exit or enhancement that modifies the selection behavior.
  Verify authorizations to ensure you have the rights to select or process the lines.
  Review the program or transaction documentation for specific instructions on line selection.

  In a transaction where you display a list of purchase orders, if you try to process without selecting any purchase order line, SAP will show W_CB140 Select a line to remind you to select at least one line.
