How To Fix CNV20201438 - &1: No duplicates due to simul. conv. in fiscal years <= &2 due to NRIV

CNV20201438 - Overview

• Message type: E = Error

• Message class: CNV20201 -

• Message number: 438

• Message text: &1: No duplicates due to simul. conv. in fiscal years <= &2 due to NRIV

What causes this issue?

&V1&: No duplicates found during simulated conversion of objects for
fiscal years <= &V2& 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
objects will become identical due to the conversion or not, and if
consequently duplicates can occur in a given table 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.

CNV20201438 - Details

• The SAP error message CNV20201438 indicates that there are no duplicates allowed during the simulation conversion for fiscal years that are less than or equal to a specified year (denoted by &2). This error is related to the data conversion process, particularly in the context of the SAP S/4HANA migration or data transfer scenarios.
  
  Cause:
  
  Data Duplication: The error typically arises when the system detects potential duplicate entries in the data that is being converted or migrated. The NRIV (Number Range Interval) is a mechanism in SAP that manages number ranges for various objects, and it plays a crucial role in ensuring that unique identifiers are maintained during data operations.
  Fiscal Year Constraints: The error specifically mentions fiscal years less than or equal to a certain year, indicating that the issue is likely tied to how data is structured or how fiscal years are defined in the system.
  
  
  Solution:
  
  Check for Duplicates: Review the data
