CNV_NCE_BAS045 - Details

• The SAP error message CNV_NCE_BAS045 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates a conflict between single mapping and number range interval mapping for a specific field or entity.
  
  Cause:
  The error arises when there is a conflict between two types of mappings:
  
  Single Mapping: This refers to a direct mapping of a single value from the source to the target.
  Number Range Interval Mapping: This involves mapping a range of values from the source to a range in the target.
  
  The conflict occurs when the same field is being mapped in both ways, leading to ambiguity in how the data should be processed. For example, if you have a single value that falls within a defined number range, the system does not know which mapping to prioritize.
  
  Solution:
  To resolve this error, you can take the following steps:
