How To Fix CNV_10020186 - Conc./frag. object &1: Interval fields do not have the same length

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 186

• Message text: Conc./frag. object &1: Interval fields do not have the same length

What causes this issue?

Fields or objects were specified as lower limit (&V2&) and as upper
limit (&V3&) for an interval for concatenated or fragmented object
&V1&. The lengths of the interval limits (given in brackets) are
different.
However the interval limits must have the same length.

How to fix this error?

Define fields or objects that have the same overall length as interval
limits.

• What is the cause and solution for SAP error message CNV_10020186 - Conc./frag. object &1: Interval fields do not have the same length ?

  The SAP error message CNV_10020186 indicates that there is a problem with the length of interval fields in a conversion or data migration process. This error typically arises during the execution of a data conversion program, particularly in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer processes.
  Cause:
  The error occurs when the interval fields being processed do not have the same length. This can happen due to:
  
  Inconsistent Data Structures: The source and target data structures may have different definitions for the interval fields, leading to a mismatch in their lengths.
  Data Mapping Issues: During the mapping of fields from the source to the target, the lengths of the interval fields may not have been aligned correctly.
  Configuration Errors: Incorrect configuration settings in the migration tool or data transfer process can lead to this error.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Structures: Verify the definitions of the interval fields in both the source and target systems. Ensure that they have the same data type and length.
  
  
  Adjust Mapping: If you are using a mapping tool, review the mapping configuration to ensure that the interval fields are correctly mapped and that their lengths match.
  
  
  Modify Data Types: If necessary, modify the data types or lengths of the interval fields in the source or target system to ensure consistency.
  
  
  Review Conversion Logic: If you are using custom conversion logic, check the code to ensure that it handles the interval fields correctly and that it does not inadvertently change their lengths.
  
  
  Test with Sample Data: Before running the full migration, test the conversion process with a small set of sample data to identify any potential issues.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using for any additional guidelines or best practices.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
