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

CNV20201436 - Overview

• 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.

CNV20201436 - Details

• 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
