How To Fix CNV344 - Conflicting non-transparent fields of table &1

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV - Conversion: Messages for Conversion Services (CNCC)

• Message number: 344

• Message text: Conflicting non-transparent fields of table &1

What causes this issue?

Table &V1& contains conflicting non-transparent fields. The
non-transparent fields of a given table are in conflict if (all
conditions must be fulfilled):
they are a part of the same transparent field,
one of them is defined to be a part of the other,
they are relevant for conversion.
Example 1:
Table X contains following conversion-relevant fields:
ABCD-COMP1
ABCD
The conflict occurs because the non-transparent field ABCD-COMP1 is
defined as a part of ABCD. This situation is dangerous because there is
a risk of converting the same data 2 times.
Example 2:
Table X contains following conversion-relevant fields:
DEFG-COMP1
DEFG-COMP2
The conflict doesn't occur because the non-transparent fields DEFG-COMP1
and DEFG-COMP2 are defined to be independent of each other. If they
hadn't been independent they whould have had to have a common part as in
example 1.
Example 3:
Table X contains following conversion-relevant fields:
HIJK-COMP1
HIJK-COMP1-COMP3
The conflict occurs because the non-transparent field HIJK-COMP1-COMP3
is defined to be a part of HIJK-COMP1 (analogous to example 1).

• What is the cause and solution for SAP error message CNV344 - Conflicting non-transparent fields of table &1 ?

  The SAP error message CNV344 indicates that there are conflicting non-transparent fields in a table during a data migration or conversion process. This typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.
  Cause:
  The error arises when there are non-transparent fields (fields that do not have a direct representation in the database, such as fields that are derived or calculated) in the source and target tables that conflict with each other. This can happen due to:
  
  Field Name Conflicts: The same field name exists in both the source and target tables but has different definitions or data types.
  Data Type Mismatches: The data types of the fields in the source and target tables do not match, leading to conflicts during the mapping process.
  Inconsistent Field Attributes: Attributes such as length, decimal places, or field properties may differ between the source and target tables.
  
  Solution:
  To resolve the CNV344 error, you can follow these steps:
  
  
  Analyze the Error Message: Check the details of the error message to identify the specific table and fields that are causing the conflict.
  
  
  Review Field Definitions: Compare the definitions of the conflicting fields in both the source and target tables. Look for differences in data types, lengths, and attributes.
  
  
  Adjust Mapping: If you are using a data migration tool, adjust the mapping configuration to ensure that the fields are correctly aligned. This may involve:
  
  Renaming fields in the source or target.
  Changing data types to ensure compatibility.
  Modifying field attributes to match.
  
  
  
  Use Transparent Fields: If possible, consider using transparent fields (fields that have a direct representation in the database) instead of non-transparent fields to avoid conflicts.
  
  
  Consult Documentation: Refer to SAP documentation or guides related to the specific migration tool you are using for additional insights and best practices.
  
  
  Testing: After making the necessary adjustments, perform a test migration to ensure that the error is resolved and that data is being migrated correctly.
