How To Fix CNV_10020103 - &1, SrcPack &2: SrcVal &3 assigned to more than one target => Tgt card. N

CNV_10020103 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 103

• Message text: &1, SrcPack &2: SrcVal &3 assigned to more than one target => Tgt card. N

What causes this issue?

The system found that the target values &V4& (and maybe others as well)
have the same target value &V3& assigned. This corresponds to a target
cardinality of N.
However source package &V2& requires a target cardinality of 1.

System Response

With regard to the data constellation, this path is not used in source
package &V2&.

How to fix this error?

The target cardinality of N may have been caused by irrelevant values.
If this is the case, maintain the relevance table accordingly and
repeat the check.

This error indicates that a source value (SrcVal) from the source package (SrcPack) is being assigned to more than one target value (Tgt card), which is not allowed in the context of the migration.
  
  Cause:
  The error arises when:

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping configuration in the migration tool to ensure that each source value is uniquely mapped to a single target value. 
  If a source value legitimately needs to map to multiple target values, consider whether the mapping
