How To Fix CNV_10020061 - Determination object &1, domain &2: Lengths are not equal (&3 <> &4)

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 061

• Message text: Determination object &1, domain &2: Lengths are not equal (&3 <> &4)

What causes this issue?

Domain &V2& has been stored for determination object &V1&. The system
found that domain &V2& has length &V4&. This value is different from
the corresponding value in the length definition &V3& of determination
object &V4&.

How to fix this error?

Store only domains of length &V3& for determination object &V1&.

• What is the cause and solution for SAP error message CNV_10020061 - Determination object &1, domain &2: Lengths are not equal (&3 <> &4) ?

  The SAP error message CNV_10020061 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is a mismatch in the lengths of the fields being compared or processed.
  Cause:
  The error message "Determination object &1, domain &2: Lengths are not equal (&3 <> &4)" suggests that:
  
  &1 refers to the determination object (e.g., a specific data structure or table).
  &2 refers to the domain of the field being processed.
  &3 is the length of the source field.
  &4 is the length of the target field.
  
  The root cause of this error is that the source and target fields have different lengths, which can lead to data truncation or loss of information during the migration process. This often happens when:
  
  The source system has a field defined with a certain length, and the target system has a field defined with a different length.
  There are inconsistencies in the data model between the source and target systems.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Fields: Check the specific determination object and domain mentioned in the error message. Identify the fields involved in the migration process.
  
  
  Compare Field Lengths: Compare the lengths of the source and target fields. You can do this by checking the data dictionary (SE11) for both the source and target systems.
  
  
  Adjust Field Lengths: If possible, adjust the field lengths in the target system to match those in the source system. This may involve:
  
  Modifying the target table structure to accommodate the longer field.
  If the target field is shorter, consider whether it is acceptable to truncate the data or if you need to extend the field length.
  
  
  
  Data Mapping: Ensure that the data mapping is correctly defined in the migration tool. If you are using a migration template, verify that the mappings are set up correctly.
  
  
  Testing: After making the necessary adjustments, perform a test migration to ensure that the error is resolved and that data is being migrated correctly.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration process you are using, as there may be additional guidelines or best practices.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions for this specific error.
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit and its functionalities, as it provides tools for data mapping and transformation.
  Data Dictionary: Use transaction SE11 to explore the data dictionary and understand the structure of the tables involved in the migration.
  
  By following these steps, you should be able to resolve the CNV_10020061 error and successfully complete your data migration.
