How To Fix CNV_10020152 - &1 &2: Lengths of SDetObject &3 and fixed value source object &4 differ

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 152

• Message text: &1 &2: Lengths of SDetObject &3 and fixed value source object &4 differ

What causes this issue?

For this DTFLD record, <DS:DE.CNV_10020_FIVAOBJ>fixed value 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 fixed value source object.
However this must be the case.

How to fix this error?

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

• What is the cause and solution for SAP error message CNV_10020152 - &1 &2: Lengths of SDetObject &3 and fixed value source object &4 differ ?

  The SAP error message CNV_10020152 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 fields for a specific data object.
  Cause:
  The error message indicates that the lengths of the source data object (SDetObject) and the fixed value source object differ. 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 for the data migration may not be set up correctly, leading to discrepancies in field lengths.
  Data Quality Issues: The source data may contain values that exceed the length defined in the target structure.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Dictionary Definitions:
  
  Verify the data types and lengths of the source and target fields in the data dictionary (transaction SE11).
  Ensure that the lengths are compatible and adjust them if necessary.
  
  
  
  Review Mapping Configuration:
  
  Check the mapping configuration in the migration tool to ensure that the fields are correctly mapped.
  If you are using a custom mapping, ensure that the lengths are defined correctly.
  
  
  
  Data Cleansing:
  
  Review the source data for any values that exceed the defined lengths of the target fields.
  Cleanse the data to ensure that all values fit within the target field lengths.
  
  
  
  Adjust Fixed Values:
  
  If the error involves fixed values, ensure that the fixed values defined in the target structure match the expected lengths.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test migration to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or the specific migration cockpit transaction to analyze and adjust the data structures.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  Documentation: Review the SAP documentation for the migration tool you are using, as it may contain specific instructions for handling data type and length mismatches.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
