SAP Error Message - Details

• Message type: E = Error

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

• Message number: 069

• Message text: Change can't be activated in target system for table &1

What causes this issue?

In the source system, one or more fields were added to the to the table.
The fields could not be added to the table in the target system.

System Response

It is not possible to replicate data for this table.

How to fix this error?

Check the system logs for errors using transaction SM21.
If a key field was changed in the source system, the database triggers
are dropped and the replication process is stopped for the table.
Examples of such a change include adding a key field or removing a key
field. In this situation, you need to restart the replication process
for the table.

Procedure for System Administrators

• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION069 - Change can't be activated in target system for table &1 ?

  The SAP error message CNV_IUUC_REPLICATION069 indicates that a change cannot be activated in the target system for a specific table. This error typically arises in the context of SAP Landscape Transformation (SLT) replication scenarios, where data is being replicated from a source system to a target system.
  Cause:
  The error can be caused by several factors, including:
  
  
  Data Consistency Issues: There may be inconsistencies in the data being replicated, such as primary key violations or foreign key constraints that are not met in the target system.
  
  
  Table Structure Mismatch: The structure of the source table and the target table may not match. This can happen if there have been changes to the table structure in the source system that have not been replicated to the target system.
  
  
  Replication Configuration Issues: There may be issues with the SLT configuration, such as incorrect settings or missing configurations that prevent the changes from being applied.
  
  
  Locking Issues: The target table may be locked by another process, preventing the activation of the changes.
  
  
  Authorization Issues: The user or process attempting to activate the changes may not have the necessary authorizations in the target system.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Consistency: Review the data being replicated for any inconsistencies. Ensure that the data in the source system adheres to the constraints defined in the target system.
  
  
  Verify Table Structure: Ensure that the structure of the source and target tables is identical. If there have been changes in the source table, you may need to update the target table accordingly.
  
  
  Review SLT Configuration: Check the SLT configuration settings to ensure that they are correct. This includes verifying the replication settings and ensuring that the necessary tables are included in the replication process.
  
  
  Check for Locks: Use transaction codes like SM12 to check for any locks on the target table. If there are locks, you may need to wait for the locking process to complete or resolve the locking issue.
  
  
  Authorization Check: Ensure that the user or process has the necessary authorizations to perform the activation in the target system.
  
  
  Monitor SLT Logs: Check the SLT logs for any additional error messages or warnings that may provide more context about the issue. You can use transaction code LTRC to access the SLT monitoring tools.
  
  
  Reinitialize Replication: If the issue persists, you may consider reinitializing the replication for the affected table. This involves stopping the replication, clearing the data, and starting the replication process again.
