• What is the cause and solution for SAP error message KM678 - Account interval &-& overlaps with &-& ?

  The SAP error message KM678 indicates that there is an overlap in the account intervals defined in the system. This typically occurs in the context of controlling (CO) or financial accounting (FI) when you are trying to define or modify account intervals for cost elements, cost centers, or other financial objects.
  Cause:
  The error arises when two or more account intervals are defined in such a way that they overlap. For example, if you have defined one interval for account range 1000 to 2000 and another for 1500 to 2500, the intervals overlap between 1500 and 2000, which triggers this error.
  Solution:
  To resolve the KM678 error, you need to check the account intervals that have been defined and ensure that there are no overlaps. Here are the steps you can take:
  
  
  Review Account Intervals: Go to the relevant configuration area in SAP (e.g., transaction codes like OKB9 for cost elements or other relevant transactions) and review the defined account intervals.
  
  
  Identify Overlapping Intervals: Look for any intervals that overlap with others. You may need to list all defined intervals to see where the overlaps occur.
  
  
  Modify Intervals: Adjust the intervals to eliminate overlaps. This may involve:
  
  Changing the start or end of an interval.
  Merging intervals if they are meant to be contiguous.
  Deleting unnecessary intervals.
  
  
  
  Test Changes: After making adjustments, test the changes to ensure that the error no longer occurs and that the system behaves as expected.
  
  
  Documentation: Document the changes made for future reference and to maintain clarity in the configuration.
