• What is the cause and solution for SAP error message DMCLG662 - DDIC timestamp comparison started ?

  The SAP error message DMCLG662 typically relates to issues with the Data Dictionary (DDIC) timestamp comparison during data migration or data loading processes. This error can occur when there is a mismatch between the timestamps of the data dictionary objects in the source and target systems, which can lead to inconsistencies or failures in data processing.
  Cause:
  
  Timestamp Mismatch: The most common cause of this error is that the DDIC objects (like tables, views, etc.) in the source system have different timestamps compared to those in the target system. This can happen if the objects were modified after the last data export or if the systems are not synchronized.
  Transport Issues: If the transport requests that include changes to the DDIC objects were not properly imported into the target system, it can lead to discrepancies.
  Versioning Issues: Different versions of the same object in different systems can also lead to this error.
  
  Solution:
  
  
  Synchronize DDIC Objects: Ensure that the Data Dictionary objects in both the source and target systems are synchronized. You can do this by:
  
  Checking the timestamps of the relevant DDIC objects in both systems.
  Transporting the latest versions of the objects from the source to the target system if necessary.
  
  
  
  Check Transport Logs: Review the transport logs to ensure that all relevant changes have been successfully imported into the target system. If any transports failed, re-import them.
  
  
  Re-Generate Objects: If the issue persists, consider re-generating the affected DDIC objects in the target system. This can be done using transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility).
  
  
  Consistency Check: Run consistency checks on the database and the Data Dictionary to identify any inconsistencies. You can use transaction codes like SE14 for database checks.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE14 (Database Utility), and SE03 (Transport Organizer).
  SAP Support: If the issue cannot be resolved internally, consider reaching out to SAP Support for assistance, providing them with detailed information about the error and the steps you have already taken.
  Documentation: Review SAP documentation related to data migration and DDIC management for best practices and guidelines.
