How To Fix CNV_IUUC_REPLICATION419 - Cannot replicate data from field &1 (table &2); see long text

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 419

• Message text: Cannot replicate data from field &1 (table &2); see long text

What causes this issue?

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

Field &V1& exceeds 1333 characters. If the length of a field exceeds
1333 characters, SAP LT Replication Server will change the type of the
field to STRING. SAP LT Replication Server uses Open SQL to calculate
the access plan, but Open SQL does not support the type STRING. This
means that SAP LT Replication Server cannot replicate data from this
field (as the access plan cannot be calculated).

• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION419 - Cannot replicate data from field &1 (table &2); see long text ?

  The SAP error message CNV_IUUC_REPLICATION419 typically occurs during data replication processes, particularly when using the SAP Landscape Transformation (SLT) replication server. This error indicates that there is an issue with replicating data from a specific field in a specified table.
  Cause:
  The error can be caused by several factors, including:
  
  Field Mismatch: The field in the source table may not match the expected data type or length in the target table.
  Data Type Issues: The data type of the field in the source system may not be compatible with the target system.
  Null Values: The source field may contain null values that are not handled properly during replication.
  Configuration Issues: There may be configuration issues in the SLT setup that prevent proper mapping of fields.
  Data Integrity Issues: There could be data integrity issues in the source table that prevent successful replication.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Field Definitions: Verify that the field definitions (data type, length, etc.) in the source and target tables match. If there are discrepancies, you may need to adjust the target table structure.
  
  
  Review SLT Configuration: Ensure that the SLT configuration is set up correctly. Check the mapping of fields and ensure that the replication settings are appropriate for the data being transferred.
  
  
  Handle Null Values: If null values are causing the issue, consider implementing logic to handle these values during replication. This may involve setting default values or modifying the replication logic.
  
  
  Check Data Integrity: Review the data in the source table for any integrity issues. Clean up any problematic records that may be causing the replication to fail.
  
  
  Consult Long Text: The error message suggests checking the long text for more details. Use transaction code SE91 to view the long text associated with the error message, which may provide additional context or specific recommendations.
  
  
  Monitor Logs: Check the SLT logs for more detailed error messages or warnings that can provide insight into what is causing the replication failure.
  
  
  Test Replication: After making changes, test the replication process to ensure that the issue has been resolved.
