How To Fix CNV_20100444 - Lower limit and upper limit in converted interval &2 will be swapped

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 444

• Message text: Lower limit and upper limit in converted interval &2 will be swapped

What causes this issue?

You included an interval limit (transaction OB74) in your mapping. As a
consequence, the interval changes from &V1& into &V2&, so that the lower
limit of the interval would become higher than the upper limit. For
this reason, lower limit and upper limit in the converted interval &V2&
will be swapped during the conversion. Information about this will be
stored to the associated log as a warning message.

How to fix this error?

Check if the accounts and interval limits are mapped correctly, and
adjust them if necessary.
Check after the conversion if interval limits must be adjusted manually.
&ADDITIONAL_HINTS&
Note that if you change an interval limit in your mapping, <ZH>all
</>fields in which this value is found will be changed, so that this
interval limit will be changed not only here, but wherever it occurs.

• What is the cause and solution for SAP error message CNV_20100444 - Lower limit and upper limit in converted interval &2 will be swapped ?

  The SAP error message CNV_20100444 indicates that there is an issue with the conversion of intervals during a data migration or conversion process. Specifically, it suggests that the lower limit and upper limit of a converted interval are swapped, which can lead to inconsistencies or errors in the data.
  Cause:
  This error typically arises in scenarios where:
  
  The data being converted has intervals defined with incorrect boundaries (e.g., the upper limit is less than the lower limit).
  There may be issues with the source data format or the mapping rules defined for the conversion.
  The conversion logic may not handle certain edge cases correctly, leading to swapped limits.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Source Data: Review the source data for the intervals being converted. Ensure that the lower and upper limits are correctly defined and that there are no cases where the upper limit is less than the lower limit.
  
  
  Review Mapping Rules: If you are using a mapping or transformation logic, verify that the rules for converting intervals are correctly implemented. Ensure that the logic correctly identifies and handles the boundaries of the intervals.
  
  
  Adjust Conversion Logic: If necessary, modify the conversion logic to handle cases where the limits might be swapped. This could involve adding checks to ensure that the lower limit is always less than or equal to the upper limit.
  
  
  Test with Sample Data: Before running the full conversion, test the process with a small set of sample data to ensure that the issue is resolved and that the intervals are being converted correctly.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific conversion program you are using. There may be known issues or patches available that address this error.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with a technical expert who specializes in data migration and conversion processes.
  
  
  Related Information:
  
  Transaction Codes: Depending on the context of the error, you may want to check transaction codes related to data migration, such as LSMW (Legacy System Migration Workbench) or other specific tools used for data conversion.
  SAP Notes: Search for relevant SAP Notes that might provide additional insights or solutions for this specific error message.
  Data Quality Checks: Implement data quality checks in your migration process to catch similar issues early on.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to ensure successful data conversion.
