How To Fix CNV_IUUC_REPLICATION172 - The configuration cannot process the compatibility view &2 of table &1

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_IUUC_REPLICATION - IUUC replication messages (HANA)

• Message number: 172

• Message text: The configuration cannot process the compatibility view &2 of table &1

What causes this issue?

You want to replicate table &V1& which has the compatibility view &V2&.
However, your configuration is using a subscription-based change data
capture mechanism that is not able to process compatibility views.

System Response

The system does not add the table to the configuration and returns an
error message.

How to fix this error?

You can try adding the compatibility view to the configuration as a CDS
view. If the compatibility view has annotations that specify it as
replication-enabled, the system will replicate the data of the
compatibility view as if this compatibility view would be one table.
Alternatively, you create another configuration that is not able to
replicate CDS views, but that is able to replicate tables with
compatibility views. Then you add the table to this configuration.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

This error typically arises during the data migration or replication process, particularly when using the SAP Landscape Transformation (SLT) replication server.
  Cause:
  The error message suggests that the system is unable to process a compatibility view of a specific table. This can occur due to several reasons, including:
  
  Incompatible Table Structure: The structure of the source table may not be compatible with the target table in the replication setup.
  Missing Configuration: The necessary configuration for the compatibility view may not be set up correctly in the SLT system.
  Data Type Mismatches: There may be data type mismatches between the source and target tables.
  Replication Settings: The replication settings for the specific table may not be correctly defined or activated.
  
  Solution:
  To resolve the error CNV_IUUC_REPLICATION172, you can follow these steps:
  
  
  Check Table Structure: Verify the structure of the source table and ensure that it matches the expected structure in the target system. Look for any discrepancies in field names, data types, or lengths.
  
  
  Review SLT Configuration: Go to the SLT configuration and check the settings for the specific table. Ensure that the compatibility view is correctly defined and that all necessary parameters are set.
  
  
  Adjust Data Types: If there are data type mismatches, consider adjusting the data types in the source or target table to ensure compatibility.
  
  
  Activate Replication: Make sure that the replication for the specific table is activated in the SLT configuration. You may need to reinitialize the replication for the table.
  
  
  Check Logs: Review the SLT logs for any additional error messages or warnings that may provide more context about the issue.
  
  
  Consult Documentation: Refer to the SAP documentation for SLT and data replication for any specific guidelines related to compatibility views and table replication.
  
  
  Contact SAP Support: If the issue persists after trying the above steps, consider reaching out to SAP support for further assistance.
