  The SAP error message LTR2_CHANGELOG084 indicates that there has been a change in the type of an attribute in the context of the SAP Landscape Transformation (SLT) Replication Server. This typically occurs when the data model of the source system has been modified, such as when an attribute's data type is altered (e.g., from integer to string) or when the attribute is added or removed.
  Cause:
  
  
  Data Model Changes: The most common cause of this error is a change in the underlying data model of the source system. This could involve:
  
  Changing the data type of a field in the source table.
  Adding new fields or removing existing ones.
  Modifying the length or precision of a field.
  
  
  
  Inconsistent Metadata: The metadata in the SLT system may not match the current structure of the source table, leading to inconsistencies.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Source Table: Verify the current structure of the source table in the source system. Look for any changes in the data types or attributes.
  
  
  Update SLT Configuration:
  
  If changes have been made to the source table, you may need to update the SLT configuration to reflect these changes.
  You can do this by reinitializing the data transfer for the affected table. This involves:
  
  Stopping the replication for the table.
  Deleting the existing configuration for that table in SLT.
  Recreating the configuration and starting the replication again.
  
  
  
  
  
  Adjust Data Types: If the data type has changed, ensure that the target system can accommodate the new data type. You may need to adjust the target table structure accordingly.
  
  
  Check for Other Errors: After making the necessary changes, monitor the SLT logs for any other related errors that may arise.
