• What is the cause and solution for SAP error message PEP258 - End date/time & & occurs before start date/time & / & ?

  The SAP error message PEP258 indicates that there is a problem with the scheduling of a project or a task within the Project System (PS) module. Specifically, it means that the end date and time you have entered for a project element (like a work package or activity) occurs before the start date and time. This is a logical inconsistency, as an activity cannot end before it starts.
  Cause:
  
  Incorrect Date Entry: The most common cause is simply entering the end date/time incorrectly, either by mistyping or misunderstanding the date format.
  System Configuration: In some cases, the system configuration or settings might lead to incorrect date calculations or defaults.
  Data Migration Issues: If data has been migrated from another system, there may be inconsistencies in date formats or values.
  Dependencies: If there are dependencies or constraints set on the project elements, they might be causing the end date to be calculated incorrectly.
  
  Solution:
  
  Check Date Entries: Review the start and end dates/times you have entered for the project element. Ensure that the end date/time is after the start date/time.
  Correct Format: Make sure that the date format you are using is consistent with the system settings (e.g., DD/MM/YYYY vs. MM/DD/YYYY).
  Review Dependencies: If there are dependencies or constraints, check if they are set correctly and adjust them if necessary.
  Re-enter Dates: If you find any discrepancies, re-enter the dates correctly and save the changes.
  Consult Documentation: If you are unsure about the correct dates or how to set them, refer to SAP documentation or consult with a project manager or SAP consultant.
  
  Related Information:
