  WRF_APC061 – "You must enter either locked or unlocked parameter"
  
  Cause:
  This error occurs in SAP Advanced Planning and Optimization (APO) or related modules when a user tries to perform an action (such as creating or changing a parameter or characteristic) without specifying whether the parameter is locked or unlocked. The system requires explicit input to determine the status of the parameter, and if neither option is provided, it raises this error.
  Typically, this happens during:
  
  Planning book or data view maintenance
  Parameter or characteristic configuration in APO Demand Planning (DP), Supply Network Planning (SNP), or other APO components
  When setting up or modifying key figures or planning parameters that require a lock status
  
  
  Solution:
  To resolve the error:
  
  
  Specify the Lock Status:
  
  When entering or modifying the parameter, explicitly select or enter whether the parameter is locked or unlocked.
  This is usually a checkbox, radio button, or dropdown field labeled something like "Lock Parameter" or "Lock Status."
  
  
  
  Check the Input Screen:
  
  Review the input screen or transaction where the error occurs.
  Ensure that the field for lock status is not left blank.
