How To Fix CNV20201436 - &1: No duplicates during simul. conversion due to NRIV

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV20201 -

• Message number: 436

• Message text: &1: No duplicates during simul. conversion due to NRIV

What causes this issue?

&V1&: No duplicates found during simulated conversion based on the
information provided in the table NRIV.
The value table for the number range object &V1& is not known or not
precise enough to allow for a check for duplicates.
The information contained in NRIV is used as the basis for the check
for duplicates. This means that the simulation cannot show for sure if
the conversion can be completed without duplicates or not.

System Response

Warning
Possible alphanumeric values within the number interval that may have
come into existence, for example, during a previous conversion, are not
considered here.

• What is the cause and solution for SAP error message CNV20201436 - &1: No duplicates during simul. conversion due to NRIV ?

  The SAP error message CNV20201436 indicates that during a simulation conversion process, the system has detected that there are no duplicates in the NRIV (Number Range Interval) table. This error typically arises in the context of data migration or conversion projects, particularly when using SAP's Conversion Tools.
  Cause:
  
  No Duplicates Found: The primary cause of this error is that the system is checking for duplicate entries in the number range intervals (NRIV) and finds none. This can happen if the data being processed does not have any overlapping or duplicate number ranges.
  Configuration Issues: There may be issues with the configuration of number ranges in the system, leading to the absence of duplicates.
  Data Integrity: The data being migrated or converted may not have been set up correctly, leading to a lack of duplicates where they are expected.
  
  Solution:
  
  Check Number Range Configuration: Review the configuration of the number ranges in the system. Ensure that the number ranges are set up correctly and that there are no gaps or overlaps that could lead to this error.
  Data Validation: Validate the data being converted to ensure that it meets the expected criteria for duplicates. If duplicates are expected, ensure that the source data is correctly populated.
  Adjust Simulation Parameters: If the simulation is not intended to check for duplicates, consider adjusting the parameters or settings of the simulation to bypass this check.
  Consult Documentation: Refer to SAP documentation or notes related to the specific conversion tool you are using. There may be specific guidelines or patches available that address this issue.
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They may have additional insights or solutions based on the specific context of your implementation.
  
  Related Information:
  
  NRIV Table: The NRIV table in SAP stores the number range intervals for various objects. Understanding how this table works and how it is populated can help in troubleshooting issues related to number ranges.
  Data Migration Tools: Familiarize yourself with the specific data migration tools and methodologies being used in your project, as they may have specific requirements or configurations that need to be adhered to.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on handling number range issues during data conversion.
  
  By following these steps, you should be able to identify the root cause of the error and implement a suitable solution.
