• What is the cause and solution for SAP error message CNV20201067 - Overlap: [&1,&2] <=> [&3,&4] ?

  The SAP error message CNV20201067 indicates an overlap issue in the context of data conversion or migration, particularly when dealing with time intervals or ranges. This error typically arises during data migration processes, such as when using the SAP S/4HANA Migration Cockpit or other data transformation tools.
  Cause:
  The error message CNV20201067 suggests that there are overlapping time intervals or ranges in the data being processed. Specifically, it indicates that two sets of data (represented by the placeholders [&1, &2] and [&3, &4]) are conflicting with each other, meaning that the time periods they cover overlap in a way that is not allowed by the system's logic or business rules.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Overlapping Ranges: Review the data that is being migrated or converted. Look for the specific entries that correspond to the placeholders in the error message. You will need to identify the time intervals or ranges that are causing the overlap.
  
  
  Adjust Data: Once you have identified the overlapping entries, you will need to adjust the data to eliminate the overlap. This could involve:
  
  Modifying the start and end dates of one or both of the conflicting entries.
  Merging entries if they represent the same entity or event.
  Deleting or archiving one of the entries if it is no longer needed.
  
  
  
  Re-run the Migration: After making the necessary adjustments to the data, re-run the migration or conversion process to see if the error persists.
  
  
  Validation: Ensure that the changes made do not violate any business rules or logic that may be enforced by the system.
  
  
  Related Information:
  
  Data Migration Tools: Familiarize yourself with the specific data migration tools you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) and their documentation for handling time intervals and data integrity checks.
  Business Rules: Understand the business rules that govern the data you are working with, as these rules will dictate how time intervals should be structured and what constitutes a valid entry.
