How To Fix CNV_10020148 - &1 &2: Lengths of SDeObject &3 and conc./frag. source object &4 differ

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 148

• Message text: &1 &2: Lengths of SDeObject &3 and conc./frag. source object &4 differ

What causes this issue?

For this DTFLD record, <DS:DE.CNV_10020_COFROBJ>concatenated or
fragmented source object</> &V4& has been assigned to
<DS:DE.CNV_10020_DTOBJ_S>source determination object</> &V3&. (The
value given in brackets is the corresponding allowed number of
characters.)
The system found that the length of the source determination object
does not correspond to the length of the concatenated or fragmented
source object. However this must be the case.

How to fix this error?

The most likely reason for this is that a wrong concatenated or
fragmented source object has been assigned. Correct the definition
accordingly.

• What is the cause and solution for SAP error message CNV_10020148 - &1 &2: Lengths of SDeObject &3 and conc./frag. source object &4 differ ?

  The SAP error message CNV_10020148 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 source and target data objects involved in the migration process.
  Cause:
  The error message indicates that the lengths of the source data object (concatenated or fragmented) and the target data object (SDeObject) do not match. This can happen due to several reasons:
  
  Data Type Mismatch: The source and target fields may have different data types or lengths defined in the data dictionary.
  Configuration Issues: The mapping configuration between the source and target objects may not be set up correctly, leading to discrepancies in expected lengths.
  Data Quality Issues: The source data may contain values that exceed the defined length of the target fields, causing the migration process to fail.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Dictionary Definitions:
  
  Verify the definitions of the source and target fields in the data dictionary (SE11). Ensure that the data types and lengths match.
  
  
  
  Review Mapping Configuration:
  
  If you are using a migration tool, check the mapping configuration to ensure that the source fields are correctly mapped to the target fields. Adjust the mapping if necessary.
  
  
  
  Data Cleansing:
  
  Inspect the source data for any values that exceed the length of the target fields. You may need to truncate or modify these values to fit the target structure.
  
  
  
  Adjust Target Field Lengths:
  
  If appropriate, consider adjusting the lengths of the target fields in the data dictionary to accommodate the source data. Be cautious with this approach, as it may have implications for other processes.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test migration to ensure that the error is resolved and that data is migrated correctly.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or the specific migration tool transaction to investigate and resolve the issue.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  Documentation: Review the documentation for the specific migration tool you are using, as it may contain troubleshooting steps or best practices for handling data length issues.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
