• What is the cause and solution for SAP error message CNV_20100330 - Overlapping cost element intervals in TCKH2: &1: &2 <> &3 ?

  The SAP error message CNV_20100330 indicates that there are overlapping cost element intervals in the table TCKH2. This typically occurs during data migration or conversion processes, particularly when using SAP's Conversion Tools (like the SAP S/4HANA Migration Cockpit or other data migration tools).
  Cause:
  The error arises when there are multiple entries in the TCKH2 table that have overlapping intervals for cost elements. This means that two or more cost elements are defined for the same period, which is not allowed. The message provides three parameters:
  
  &1: The cost element that is causing the issue.
  &2: The start date of the first interval.
  &3: The end date of the first interval.
  
  Solution:
  To resolve this error, you need to ensure that the cost element intervals do not overlap. Here are the steps you can take:
  
  
  Identify Overlapping Entries:
  
  Use transaction codes like SE16 or SE11 to view the contents of the TCKH2 table.
  Look for entries with the same cost element that have overlapping date ranges.
  
  
  
  Adjust the Intervals:
  
  Modify the date ranges of the cost elements to ensure that they do not overlap. This may involve changing the start and end dates of one or more entries.
  Ensure that each cost element has a unique interval that does not conflict with others.
  
  
  
  Data Validation:
  
  After making adjustments, validate the data to ensure that there are no remaining overlaps.
  You can run a report or query to check for any remaining overlapping intervals.
  
  
  
  Re-run the Migration Process:
  
  Once the overlaps are resolved, re-run the migration or conversion process that triggered the error.
