• What is the cause and solution for SAP error message WZ459 - Enter an end date that is before the start date ?

  SAP Error Message:
  
  WZ459 - Enter an end date that is before the start date
  
  Cause:
  This error occurs when you enter an end date that is earlier than or equal to the start date in a date range field within SAP. The system expects the end date to be after the start date to maintain logical consistency in date intervals.
  
  Explanation:
  
  In many SAP transactions or master data maintenance screens (e.g., HR infotypes, validity periods for master data, scheduling, or time-dependent data), you are required to enter a validity period or a date range.
  The start date marks the beginning of the period.
  The end date marks the end of the period.
  The system validates that the end date is strictly greater than the start date.
  If the end date is the same as or before the start date, the system throws message WZ459.
  
  
  Solution:
  
  Check the dates entered: Ensure that the end date is later than the start date.
  Correct the end date to a date that is after the start date.
  If you intend to enter a single day period, the end date should be the same as the start date only if the system allows it; otherwise, adjust accordingly.
  If the dates are populated automatically (e.g., by a program or interface), verify the logic that sets these dates.
  
  
  Related Information:
  
  This message is common in HR modules (Personnel Administration, Time Management) when maintaining infotypes with validity periods.
  It can also appear in other modules where date ranges are used (e.g., Material Master, Vendor Master, Scheduling).
  The message class WZ is often related to HR or time-dependent data.
  Always ensure date intervals are logically consistent to avoid this error.
  If you are using custom programs or interfaces, add validation to prevent invalid date ranges before posting data to SAP.
  
  
  Example:
  
  Start Date: 01.01.2024  
  End Date: 31.12.2023 ? Error WZ459 because end date is before start date.  
  Correct End Date: 31.12.2024 ? No error.
