How To Fix CNV_NCE_BAS246 - Mapping values are not valid; conversion simulation is not possible

CNV_NCE_BAS246 - Overview

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 246

• Message text: Mapping values are not valid; conversion simulation is not possible

What causes this issue?

The Number Conversion Engine has detected that mapping values for a
subobject of the corresponding number range object have been changed
since the last analysis run (e.g. new mapping values have been created).
Existing mapping values for number range objects are not more valid.
Initialization of mapping values for number range objects is required.

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?

Execute the activity 'Initialize Mapping Values for Number Range
Objects' again. The Number Conversion Engine will update mapping values
for the relevant number range objects. You need to execute the activity
'Specify Mapping Values for Number Range Objects' after that again.

CNV_NCE_BAS246 - Details

• The SAP error message CNV_NCE_BAS246 indicates that there is an issue with the mapping values during a data conversion process, typically in the context of a data migration or conversion project using SAP's tools. This error suggests that the values being mapped do not conform to the expected format or valid range, making it impossible to simulate the conversion.
  Causes:
  
  Invalid Mapping Values: The values specified in the mapping do not exist in the target system or are not valid according to the defined mapping rules.
  Data Type Mismatch: The source and target fields may have incompatible data types, leading to conversion issues.
  Missing Configuration: Required configuration settings or mapping definitions may be missing or incorrectly set up.
  Inconsistent Data: The source data may contain inconsistencies or errors that prevent successful mapping.
  Custom Logic Issues: If there are custom conversion routines or logic, they may not be functioning correctly.
  
  Solutions:
  
  Check Mapping Configuration: Review the mapping configuration to
