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

CNV_10020148 - Overview

• 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.

• 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
