• What is the cause and solution for SAP error message RQ391 - Freuquency in days too small to set to previous day off/working day ?

  The SAP error message RQ391, which states "Frequency in days too small to set to previous day off/working day," typically occurs in the context of scheduling or planning within SAP, particularly when dealing with maintenance plans or task scheduling.
  Cause:
  This error usually arises when the frequency of a maintenance plan or task is set to a value that is not compatible with the calendar settings or the defined working days. For example, if you have a maintenance plan that is set to run every day, but the system is trying to schedule it on a day that is marked as a non-working day, it will trigger this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Frequency Settings: Review the frequency settings of the maintenance plan or task. Ensure that the frequency is appropriate for the working days defined in your calendar.
  
  
  Adjust Working Days: If the frequency is correct, check the calendar settings to ensure that the working days are defined correctly. You may need to adjust the calendar to include more working days or change the frequency of the task.
  
  
  Change Scheduling Parameters: If the task is set to run too frequently, consider increasing the frequency to a value that aligns with the working days. For example, if it is set to run every day, you might change it to every two or three days.
  
  
  Review Task Dependencies: If the task is dependent on other tasks or events, ensure that those dependencies are also set correctly and do not conflict with the working days.
  
  
  Use Transaction Codes: You can use transaction codes like IP02 (Change Maintenance Plan) or IP10 (Schedule Maintenance Plan) to make the necessary adjustments.
  
  
  Consult Documentation: If you are unsure about the settings, refer to SAP documentation or consult with your SAP administrator for guidance on how to configure maintenance plans and scheduling.
