How To Fix CNV_NCE_BAS169 - Number &1: one-to-one and NR mappings have different target intervals

CNV_NCE_BAS169 - Overview

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 169

• Message text: Number &1: one-to-one and NR mappings have different target intervals

What causes this issue?

You have created a one-to-one mapping for the number that belongs to a
certain number range interval. There exists a number range mapping for
this interval and the target number of the one-to-one mapping does not
belong to the target interval of the number range mapping.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Change the boundaries of the target interval from the number range
mapping so that the target number of the one-to-one mapping fits into
it, or choose another target number for the corresponding source number.

CNV_NCE_BAS169 - Details

• The SAP error message CNV_NCE_BAS169 indicates that there is a conflict in the mapping configuration for a conversion project, specifically regarding the target intervals for one-to-one mappings and non-redundant (NR) mappings. This error typically arises during data migration or conversion processes, particularly when using SAP's data migration tools.
  
  Cause:
  The error occurs when:
  
  You have defined a one-to-one mapping for a certain data element, which specifies a specific target interval.
  At the same time, there is a non-redundant mapping (NR mapping) for the same data element that specifies a different target interval.
  The system detects that these two mappings cannot coexist because they are trying to map the same source value to different target values or ranges.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Mappings: Check the mappings defined in your conversion project. Look for the specific data element mentioned in the error message (indicated by &1).
