How To Fix CNV_10020104 - &1, SrcPack &2: TgtVal &3 assigned to more than one source => Src card. N

CNV_10020104 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 104

• Message text: &1, SrcPack &2: TgtVal &3 assigned to more than one source => Src card. N

What causes this issue?

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

CNV_10020104 - Details

• The SAP error message CNV_10020104 typically occurs during data migration processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that a target value (TgtVal) is assigned to more than one source value (SrcPack), which can lead to ambiguity in the data mapping process.
  
  Cause:
  The error arises when:
  
  A target value in the migration mapping is linked to multiple source values. This can happen if the source data is not unique or if there are multiple records in the source that map to the same target value.
  There may be issues with the data quality in the source system, such as duplicates or inconsistencies.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Mapping Configuration:
  
  Check the mapping configuration in the migration tool to ensure that each target value is uniquely assigned to a single source value.
  Identify the source values that are causing the conflict.
