• What is the cause and solution for SAP error message WP800 - First page already reached ?

  SAP Error Message:
  
  WP800 - First page already reached
  
  Cause:
  The error message WP800 - First page already reached typically occurs in SAP when you are navigating through a list or a report (such as a list of work orders, purchase orders, or any paginated data) and you attempt to go to the previous page while you are already on the first page. Since there is no page before the first page, the system raises this message to indicate that you cannot go back any further.
  
  When does it occur?
  
  While using transaction codes or reports that display data in multiple pages.
  When using navigation buttons like "Previous Page" or "Page Up" on the first page.
  In work order processing (IW32/IW33) or other logistics transactions where lists are paginated.
  
  
  Solution:
  
  Avoid pressing the "Previous Page" button or equivalent navigation control when you are already on the first page.
  If you want to refresh or re-display the first page, use the "Refresh" or "Execute" button instead of navigating backward.
  If you are scripting or automating SAP GUI actions, add logic to check the current page number before attempting to navigate backward.
  In custom developments or enhancements, ensure that navigation logic handles boundary conditions properly.
  
  
  Related Information:
  
  This message is informational and does not indicate a system error or malfunction.
  It is part of SAP's standard navigation control to prevent invalid page navigation.
  Similar messages exist for the last page, e.g., WP801 - Last page already reached.
  If you encounter this message frequently and it disrupts your workflow, consider reviewing your navigation steps or customizing the user interface to disable backward navigation on the first page.
  For developers, check the code handling the list display and paging logic (e.g., ALV grid or classical lists) to ensure proper page boundary checks.
