How To Fix CNV_10020766 - &1, &2: Length of source field/obj. &3 and SDetObject &4 differ

CNV_10020766 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 766

• Message text: &1, &2: Length of source field/obj. &3 and SDetObject &4 differ

What causes this issue?

The rule assigned to the component consists of a determination defined
in &V2&. The length of the passed parameter &V3& for the source
field/object doesn't match the length of the source determination object
&V4& (the lengths are shown in brackets).

How to fix this error?

In transaction CNV_10020_RDTOBJ, assign a passed parameter with a length
that matches the length of the source determination object.

CNV_10020766 - Details

• The SAP error message CNV_10020766 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data transfer tools. This error indicates a mismatch in the length of the source field or object compared to the target structure or object.
  
  Cause:
  The error message CNV_10020766 is triggered when:
  
  The length of a source field (or object) does not match the expected length in the target structure.
  There may be a discrepancy in the data types or lengths defined in the source and target systems.
  The source data may contain values that exceed the defined length in the target structure, leading to truncation or data loss.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Field Lengths: 
  
  Review the field definitions in both the source and target systems. Ensure that the lengths of the fields match.
  If the source field is longer than the target field, consider truncating the data
