• What is the cause and solution for SAP error message W_CB235 - Select only one line ?

  SAP Error Message:
  
  W_CB235 - Select only one line
  
  Cause:
  This warning message appears when a user is expected to select exactly one line (record) from a list or table, but either no line or multiple lines have been selected. The system requires a single selection to proceed with the intended operation.
  
  When does it occur?
  
  When executing a function or transaction that requires a single line item selection.
  For example, in selection screens, list displays, or when choosing an entry from a list of values (F4 help).
  Common in modules like MM, SD, FI, or custom reports where the logic expects one record to process.
  
  
  Solution:
  
  Ensure that you select exactly one line before proceeding.
  If multiple lines are selected, deselect all but one.
  If no line is selected, select one line.
  If the selection is done via checkboxes or row highlights, verify the correct selection method.
  If this happens in a custom program or report, check the selection logic or coding to enforce single selection.
  
  
  Related Information:
  
  This message is a warning (W) type, so it may allow you to continue after acknowledging it, but the process might not work correctly without a single selection.
  The message class is usually CB or related to the specific module or program.
  In custom developments, this message can be triggered by the function module MESSAGE with message number 235 in message class CB.
  To debug or analyze, check the selection screen or list processing logic in the ABAP code.
  If you are a developer, you can search for MESSAGE W_CB235 in the code to find where the check is implemented.
