• What is the cause and solution for SAP error message WRF_DYNAMIC_SELECT018 - The lower limit is greater than the upper limit ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_DYNAMIC_SELECT018: The lower limit is greater than the upper limit
  
  Cause:
  This error occurs when a selection range is entered incorrectly in a dynamic selection or selection screen. Specifically, the lower limit (from value) of a range is greater than the upper limit (to value). For example, if you enter a date range where the start date is after the end date, or a numeric range where the "from" value is larger than the "to" value, the system raises this error.
  
  Explanation:
  
  SAP selection screens and dynamic selections often allow users to specify ranges for fields.
  The system expects the lower limit (start of the range) to be less than or equal to the upper limit (end of the range).
  If this logical condition is violated, the system cannot process the selection correctly and throws this error.
  
  
  Solution:
  
  
  Check the selection criteria entered:
  
  Verify the values entered in the selection screen or dynamic selection.
  Ensure that for every range, the "from" value is less than or equal to the "to" value.
  
  
  
  Correct the input:
  
  Adjust the values so that the lower limit is less than or equal to the upper limit.
  For example, if you entered a date range from 2024-05-10 to 2024-05-01, change it to 2024-05-01 to 2024-05-10.
  
  
  
  If the error occurs programmatically:
  
  Check the ABAP code or dynamic selection logic that sets the range values.
  Make sure the code assigns the correct order to the range limits.
  Add validation logic to prevent incorrect ranges from being passed.
  
  
  
  
  Related Information:
  
  This error is common in reports, transactions, or custom programs where dynamic selections or selection screens are used.
  The message class is usually WRF_DYNAMIC_SELECT.
  Similar errors can occur for other range fields like numeric ranges, date ranges, or character ranges.
  Always validate user input or programmatically set ranges before executing queries or reports.
  
  
  Example:
  If you have a selection screen with a date range field:
  
  
  
  From Date
  To Date
  
  
  
  
  2024-06-15
  2024-06-10
  
  
  
  This will trigger the error because 2024-06-15 (lower limit) > 2024-06-10 (upper limit).
  Correct it to:
  
  
  
  From Date
  To Date
  
  
  
  
  2024-06-10
  2024-06-15
