What causes this issue?

intervals is not actually contained in the other interval because its
upper or lower limit falls on the upper or lower limit of the other.
This means that the smaller interval is not truely demarcated within
the larger interval. A true demarcation must be maintained.

• What is the cause and solution for SAP error message F9630 - Interval is within other interval, a true demarcation does not exist ?

  The SAP error message F9630, "Interval is within other interval, a true demarcation does not exist," typically occurs in the context of financial transactions, particularly when dealing with fiscal periods, posting periods, or other time-based intervals in SAP.
  Cause:
  This error arises when you attempt to create or modify a time interval (such as a posting period or fiscal year) that overlaps with an existing interval. Specifically, it indicates that the new interval you are trying to define is completely contained within another existing interval, which violates the rules of interval management in SAP. 
  For example, if you have an existing interval from January 1 to March 31, and you try to create a new interval from February 1 to February 28, SAP will throw this error because the new interval is entirely within the existing one.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Existing Intervals: Check the existing intervals in the relevant configuration or transaction. Identify the intervals that are causing the conflict.
  
  
  Adjust the New Interval: Modify the new interval you are trying to create so that it does not overlap with existing intervals. Ensure that it starts after the end of the existing interval or ends before the start of the existing interval.
  
  
  Delete or Modify Existing Intervals: If the existing intervals are no longer needed, consider deleting or modifying them to allow for the new interval. However, be cautious with this approach, as it may affect other transactions or reports.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing intervals in your version of SAP.
  
  
  Check Configuration Settings: If you are working with fiscal year settings or posting periods, ensure that your configuration settings are correct and align with your organization's financial calendar.
  
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may be using transaction codes like OB29 (for fiscal year variant) or OB52 (for posting periods).
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  User Roles and Authorizations: Ensure that you have the necessary permissions to create or modify intervals in the system.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in financial modules.
