• What is the cause and solution for SAP error message RQ280 - Due to calendar specifics, 'skip Saturday/Sunday' is ignored ?

  The SAP error message RQ280, which states "Due to calendar specifics, 'skip Saturday/Sunday' is ignored," typically occurs in the context of scheduling or planning activities within SAP, particularly when working with production planning, project management, or similar modules that involve date calculations.
  Cause:
  This error arises when the system encounters a situation where the calendar settings do not allow for the skipping of weekends (Saturday and Sunday) as specified in the scheduling parameters. This can happen due to:
  
  
  Calendar Configuration: The factory calendar or work schedule may not be set up to recognize weekends as non-working days. This can occur if the calendar is configured to treat all days as working days or if specific holidays are not defined correctly.
  
  
  Task Scheduling: If a task or operation is scheduled to start or finish on a weekend, and the system is set to skip weekends, it may not be able to do so due to the calendar settings.
  
  
  Project or Production Settings: The settings for the project or production order may not align with the calendar settings, leading to conflicts in scheduling.
  
  
  Solution:
  To resolve the RQ280 error, you can take the following steps:
  
  
  Check Calendar Settings:
  
  Go to the transaction code SCAL (Maintain Calendar) to review the factory calendar settings.
  Ensure that Saturday and Sunday are marked as non-working days if you intend to skip them in scheduling.
  
  
  
  Review Work Schedule:
  
  Check the work schedule for the relevant plant or work center to ensure that weekends are defined correctly.
  You can use transaction code CR01 (Create Work Center) or CR02 (Change Work Center) to review and adjust the work schedule.
  
  
  
  Adjust Scheduling Parameters:
  
  When creating or modifying a production order or project, ensure that the scheduling options are set correctly. If you want to skip weekends, make sure that the option is selected and that the calendar supports it.
  
  
  
  Check for Holidays:
  
  Ensure that any holidays are correctly defined in the calendar, as they can also affect scheduling.
  
  
  
  Testing:
  
  After making changes, test the scheduling again to see if the error persists. You may need to re-run the scheduling process for the affected orders or tasks.
  
  
  
  Related Information:

  Documentation: Refer to SAP documentation or help files for detailed information on calendar settings and scheduling options.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message, as there may be specific fixes or recommendations provided by SAP.
