How To Fix CNV_NCE_BAS102 - NR interval &1: unable to define interval limits due to ambiguity

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 102

• Message text: NR interval &1: unable to define interval limits due to ambiguity

What causes this issue?

The system cannot determine the target interval limits automatically.

System Response

The program generates number range interval mappings on basis of
existing subobject mappings. If a number range interval exists in a
source subobject but does not exist in a target one, the program creates
a corresponding interval in the target subobject and determines its
limits automatically. However, this determination is not possible if
there are several source subobjects that have the same interval with
different number limits.
Example:
Subobject mapping (company codes):
A001 -> A002
A002 -> A002 (priority company code)
A003 -> A002
Number range intervals (interval 01/2010 does not exist in company code
A002):
RF_BELEG,,A001,,01,,2010,,1000000000,,1999999999
RF_BELEG,,A003,,01,,2010,,2000000000,,2999999999
The program cannot define number range interval limits of the target
interval A002/01/2010, because it is unclear what variant (A001 or A003)
should be chosen.
Comment: if a target subobject differs from a priority subobject,
determination of target number range intervals is based on a priority
subobject.

How to fix this error?

You should define number range interval limits later in the activity
'Specify Mapping Values for Number Range Objects'.

• What is the cause and solution for SAP error message CNV_NCE_BAS102 - NR interval &1: unable to define interval limits due to ambiguity ?

  The SAP error message CNV_NCE_BAS102 with the description "NR interval &1: unable to define interval limits due to ambiguity" typically occurs during data conversion processes, particularly when using the SAP Data Migration tools or during the execution of certain conversion programs. This error indicates that there is an issue with defining the limits of a numeric range (NR interval) due to ambiguous or conflicting data.
  Cause:
  
  Ambiguous Data: The data being processed may contain overlapping or conflicting values that make it impossible for the system to determine clear upper and lower limits for the interval.
  Incorrect Configuration: There may be misconfigurations in the settings or parameters used for the conversion process.
  Data Quality Issues: The source data may have inconsistencies, such as missing values, duplicates, or incorrect formats that lead to ambiguity.
  Custom Code or Enhancements: If there are custom developments or enhancements in the conversion process, they may introduce unexpected behavior.
  
  Solution:
  
  Review Data: Check the source data for any inconsistencies or ambiguities. Look for overlapping ranges or missing values that could cause the issue.
  Adjust Configuration: Review the configuration settings for the conversion program. Ensure that the parameters for defining intervals are set correctly and do not conflict with each other.
  Data Cleansing: Perform data cleansing to resolve any issues in the source data. This may involve removing duplicates, filling in missing values, or correcting data formats.
  Debugging: If you have access to the development environment, consider debugging the conversion program to identify where the ambiguity arises.
  Consult Documentation: Refer to SAP documentation or notes related to the specific conversion program you are using. There may be known issues or additional configuration steps required.
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific scenario.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on similar issues.
  Data Migration Tools: Familiarize yourself with the SAP Data Migration tools and their configuration options, as they often have specific requirements for data formats and structures.
  Testing: After making changes, conduct thorough testing to ensure that the issue is resolved and that the data conversion proceeds without further errors.
  
  By following these steps, you should be able to identify and resolve the cause of the CNV_NCE_BAS102 error in your SAP environment.
