W0CSRS026 - Details

• SAP Error Message:
  W0CSRS026 – Set one key in the selection box as a default
  
  
  Cause:
  This warning message appears when a selection screen or a selection box (such as a dropdown or radio button group) in a custom or standard SAP report or transaction does not have a default value set. SAP requires that at least one key (option) in the selection box be pre-selected as the default to avoid ambiguity and ensure the user interface behaves predictably.
  
  Explanation:
  
  In selection screens, especially those with multiple options (like radio buttons or dropdown lists), SAP expects one option to be pre-selected.
  If no default is set, the system raises this warning to prompt the developer or configurator to specify a default value.
  This helps users by providing a starting point and prevents errors or confusion during execution.
  
  
  
  Solution:
  
  
  Set a Default Value in the Selection Box:
  
  In the ABAP code or screen configuration, assign a default value to the parameter
