• What is the cause and solution for SAP error message OL630 - Data model was deleted ?

  The SAP error message OL630, which states "Data model was deleted," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when a data model that is being referenced or used has been deleted or is no longer available in the system. This can happen for various reasons, such as changes in the data model configuration, deletion of objects, or issues during data loading processes.
  Causes:
  
  Manual Deletion: The data model was manually deleted by a user or during a system cleanup process.
  Transport Issues: If the data model was transported from one system to another, it might not have been included in the transport request.
  System Migration: During system upgrades or migrations, certain objects may not have been migrated correctly.
  Configuration Changes: Changes in the configuration or structure of the data model that lead to the model being invalidated or deleted.
  Data Source Issues: The underlying data source for the data model may have been deleted or modified.
  
  Solutions:
  
  Check Object Existence: Verify if the data model still exists in the system. You can do this by navigating to the relevant transaction (e.g., RSA1 for BW) and checking the data model in the appropriate area (e.g., InfoProviders, DataSources).
  Restore from Backup: If the data model was deleted accidentally, you may need to restore it from a backup or re-create it based on the original specifications.
  Review Transport Requests: If the issue arose after a transport, check the transport requests to ensure that the data model was included and correctly transported.
  Recreate the Data Model: If the data model cannot be restored, you may need to recreate it manually, ensuring that all dependencies and configurations are correctly set.
  Check for Dependencies: Ensure that any dependent objects (like InfoObjects, DataSources, etc.) are also intact and correctly configured.
  Consult Logs: Review system logs (e.g., SLG1) for any additional error messages or warnings that might provide more context about the deletion.
