How To Fix CNV104 - Contradictory entries for derivation type for the different packages.

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 104

• Message text: Contradictory entries for derivation type for the different packages.

What causes this issue?

When executing a conversion, you can specify that you want the
conversion to take place only in certain organizational units (such as
company codes or controlling areas). If you do so, the system checks
during the conversion to which organizational unit each record of a
table belongs. Depending on whether its organizational unit participates
in the conversion or not, each record is either converted or retained
intact.
For the shipment packages, it is possible to specify if this function is
active for the package, if it can be activated, if it must not be
activated or if the decision on whether to activate the function or not
is taken during the conversion depending on the package settings.
If activating the function is allowed for a package, the system asks you
during the package creation process if you want to activate the
function, and if yes, by which organizational unit (company code or
controlling area) delimitation should take place.

System Response

The conversion package is meant to be created based on multiple shipment
packages. When checking the settings for delimitation by organizational
units, the system found that the settings for the different shipment
packages are not compatible:
For each conversion package, exactly one setting for delimitation by
organizational units exists. If multiple shipment packages are meant to
be run together, their settings must be harmonized. In the given case,
this is not possible because different derivation types have been
specified for the different packages.

• What is the cause and solution for SAP error message CNV104 - Contradictory entries for derivation type for the different packages. ?

  The SAP error message CNV104 indicates that there are contradictory entries for derivation types across different packages in the context of a data migration or conversion process. This error typically arises during the execution of a conversion program, particularly when using SAP's Conversion Tools or during the data migration process.
  Cause:
  The error is usually caused by one or more of the following issues:
  
  
  Inconsistent Configuration: Different packages may have conflicting settings or configurations for the same derivation type. This can happen if the derivation rules are not uniformly defined across the packages.
  
  
  Duplicate Entries: There may be duplicate entries for the same derivation type in different packages, leading to ambiguity in how the system should process the data.
  
  
  Incorrect Mapping: The mapping of fields or values between the source and target systems may not be correctly defined, causing the system to encounter contradictory information.
  
  
  Data Integrity Issues: There may be underlying data integrity issues in the source data that lead to conflicting derivation types.
  
  
  Solution:
  To resolve the CNV104 error, you can follow these steps:
  
  
  Review Configuration: Check the configuration settings for the derivation types in all relevant packages. Ensure that they are consistent and correctly defined.
  
  
  Identify Conflicts: Use transaction codes or reports to identify where the contradictory entries are located. This may involve checking the configuration tables or using specific SAP tools designed for data migration.
  
  
  Eliminate Duplicates: If there are duplicate entries, remove or consolidate them to ensure that there is only one valid entry for each derivation type.
  
  
  Correct Mapping: Review the mapping of fields and values to ensure that they align correctly between the source and target systems. Make necessary adjustments to the mapping rules.
  
  
  Data Cleansing: If there are data integrity issues, perform data cleansing on the source data to resolve any inconsistencies before attempting the migration again.
  
  
  Testing: After making the necessary changes, run a test migration to ensure that the error has been resolved and that the data is being processed correctly.
