How To Fix CNV_10020092 - &1 &2: Required length of a determination value is too big

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 092

• Message text: &1 &2: Required length of a determination value is too big

What causes this issue?

For &V1& &V2&, at least one determination object has been defined whose
length exceeds the length of the widest object table. &V1& &V2& cannot
be used.

How to fix this error?

When defining the determination objects, consider the allowed maximum
length. You can find the allowed maximum length for the source
determination object in domain CNV_10020_DTVALS_X (or table field
CNV_10020_LOR_X-DTVAL_S) and for the target determination object in
domain CNV_10020_DTVALT_X (or table field CNV_10020_LOR_X-DTVAL_T).

• What is the cause and solution for SAP error message CNV_10020092 - &1 &2: Required length of a determination value is too big ?

  The SAP error message CNV_10020092 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 the length of a determination value exceeds the maximum allowed length for that field in the target system.
  Cause:
  The error is caused by one of the following reasons:
  
  Data Length Exceeded: The data being migrated has a value that is longer than the defined length for the corresponding field in the target system.
  Mapping Issues: There may be a mismatch in the data mapping between the source and target systems, leading to incorrect data lengths.
  Configuration Errors: The target system may have been configured with stricter length requirements than the source system.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Field Lengths: Review the field definitions in the target system to determine the maximum allowed length for the field that is causing the error. Compare this with the data being migrated.
  
  
  Data Cleansing: If the data in the source system exceeds the allowed length, you may need to cleanse or truncate the data before migration. This can involve:
  
  Shortening the values.
  Removing unnecessary characters or spaces.
  Ensuring that the data conforms to the target system's requirements.
  
  
  
  Adjust Mapping: If the error is due to incorrect mapping, review the mapping configuration in the migration tool to ensure that the source fields are correctly mapped to the target fields.
  
  
  Modify Target Field Length: If appropriate, consider adjusting the field length in the target system to accommodate the incoming data. This should be done with caution and in accordance with your organization's data governance policies.
  
  
  Testing: After making the necessary adjustments, perform a test migration with a smaller dataset to ensure that the error is resolved before proceeding with the full migration.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error message.
  Migration Tools Documentation: Review the documentation for the specific migration tool you are using, as it may contain specific instructions or best practices for handling data length issues.
  Community Forums: Engage with SAP community forums or support channels for insights from other users who may have encountered and resolved similar issues.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to successfully complete your data migration.
