• What is the cause and solution for SAP error message W0094 - Select one key in select box as the default ?

  SAP Error Message:
  
  W0094 - Select one key in select box as the default
  
  Cause:
  This warning message appears when a selection screen or a selection option in an SAP program or report has a select-option or parameter with multiple possible values, but no default value (single key) has been set as the default. In other words, the system expects that among the multiple possible entries in a select-option, one should be marked as the default selection key, but none has been specified.
  This often happens in custom reports or transactions where select-options are defined, and the developer or user has not assigned a default value or key for the select-option.
  
  Explanation:
  
  Select-options in SAP allow users to select multiple values or ranges.
  When a select-option is displayed on the selection screen, SAP can highlight or pre-select a default value to guide the user.
  If no default is set, SAP issues this warning to prompt the developer or user to specify a default key.
  This helps improve usability by pre-filling the selection screen with a meaningful default.
  
  
  Solution:
  
  
  For Developers:
  
  Review the select-options or parameters in the ABAP code.
  Assign a default value or key to the select-option using the SELECT-OPTIONS or PARAMETERS statement with the DEFAULT addition.
  Example:
  SELECT-OPTIONS: s_matnr FOR mara-matnr DEFAULT '000000000000001234'.
  
  Alternatively, set the default value dynamically in the AT SELECTION-SCREEN OUTPUT event:
  AT SELECTION-SCREEN OUTPUT.
    IF s_matnr[] IS INITIAL.
      s_matnr-low = '000000000000001234'.
      s_matnr-sign = 'I'.
      s_matnr-option = 'EQ'.
      APPEND s_matnr.
    ENDIF.
  
  Ensure that among the multiple keys, one is marked as default.
  
  
  
  For Users:
  
  If you encounter this message during report execution, it is usually a developer issue.
  You can manually enter a value in the select-option to proceed.
  Inform your SAP development team to set a default value to avoid this warning.

  Message Class: W (Warning)

  Check SAP Notes or documentation if this message appears in standard SAP programs, as it might indicate a missing configuration or patch.
  
  
  Summary:
  
  Cause: No default key/value set in a select-option on the selection screen.
  Solution: Assign a default value/key in the select-option definition or dynamically in the selection screen logic.
  Effect: Improves usability by pre-selecting a meaningful default value.
