  SAP Error Message:
  WZ097 - Specify an expression for date and time
  
  
  Cause:
  This warning message appears when a date and/or time field in a selection screen or a report is left empty or not properly specified, and the system expects an expression or value for that field. Typically, this happens in ABAP programs or SAP standard transactions where date/time parameters are mandatory or where the logic requires a valid date/time expression to proceed.
  
  Explanation:
  
  The system requires a valid date/time expression to perform operations such as filtering data, scheduling, or calculations.
  If the user or program does not provide this, the system issues the warning WZ097 to prompt for a correct input.
  This message is often triggered in selection screens where date/time fields are used as input parameters.
  
  
  
  Solution:
  
  
  User Action:
