  The SAP error message CNV_NCE_BAS002 indicates that there is a discrepancy between the values in two tables: TNRO (which typically contains number range objects) and KB (which may refer to a custom or specific table related to number ranges or other business objects). The error message specifies that there is a difference in the value of a particular field (denoted as &1) between these two tables, with TNRO having a value of &2 and KB having a value of &3.
  Cause:
  
  
  Data Inconsistency: The primary cause of this error is a mismatch in the data between the TNRO and KB tables. This could happen due to:
  
  Manual data entry errors.
  Incomplete or incorrect data migration during system upgrades or data transfers.
  Custom developments or modifications that have not been properly synchronized.
  
  
  
  Configuration Issues: There may be configuration issues in the number range settings that lead to inconsistencies between the two tables.
  
  
  Custom Code: If there are custom programs or enhancements that manipulate number ranges, they may not be correctly handling the values, leading to discrepancies.
  
  
  Solution:
  
  
  Data Validation: 
  
  Check the values in both tables for the specified field. You can use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to view the contents of the TNRO and KB tables.
  Identify the specific records that are causing the discrepancy.
  
  
  
  Correct the Data: 
  
  If the discrepancy is due to incorrect data, update the values in either the TNRO or KB table to ensure they match.

  Review Configuration: 
  
  Check the configuration settings for number ranges in the relevant transaction codes (e.g., SNRO for number range objects).
  Ensure that the number range objects are correctly defined and that there are no overlaps or gaps.
  
  
  
  Custom Code Review: 
  
  If there are custom developments, review the code to ensure that it correctly handles number range assignments and does not introduce inconsistencies.
