• What is the cause and solution for SAP error message /PM0/ABB_MESSAGES628 - Main due date cannot be a leap day ?

  The SAP error message /PM0/ABB_MESSAGES628 indicating that "Main due date cannot be a leap day" typically arises in the context of project management or scheduling within SAP systems. This error occurs when a date that falls on February 29 (a leap day) is set as a main due date for a project or task, which is not allowed by the system.
  Cause:
  
  Leap Year Date: The main due date is set to February 29, which only occurs in leap years (e.g., 2020, 2024). If the system does not support leap days for certain operations or calculations, it will trigger this error.
  Business Rules: The business logic or configuration in the SAP system may not allow leap days for due dates, possibly due to specific project management rules or constraints.
  
  Solution:
  
  Change the Due Date: Modify the main due date to a valid date that is not February 29. You can choose February 28 or March 1, depending on your scheduling needs.
  Check Configuration: Review the project management settings in your SAP system to see if there are any configurations that restrict the use of leap days. If necessary, consult with your SAP administrator or support team to understand the business rules in place.
  Custom Development: If leap day handling is essential for your business processes, consider discussing with your SAP development team about customizing the logic to accommodate leap days, although this may require significant changes and testing.
  
  Related Information:
  
  Leap Year Calculation: Leap years occur every four years, except for years that are divisible by 100 but not by 400. This means that while 2000 was a leap year, 1900 was not.
